## Linear interpolation

Hi Dario I am not sure that Cadence/spectre can do the linear interpolation. What you should do is a interpolation of your points in matlab, and then feed this to Vdc in cadence. hope it helps

## Pspice Etable produces wrong duty ratio signal

A table is actually a transfer function in forms of value pairs. The first value of each pair is input (which is difference between IN+ and IN-) and second value is output. linear interpolation is performed between entries. The difference between your blue and green inputs never reaches till -15V and 15v, so output would not be affected. Try diff

## How to calculate the floating point in verilog?

I would also add CORDIC algorithm and look-up table (optionally with linear interpolation) to the candidate list. Of course it doesn't matter if you are using Verilog or a different hardware description method.

## FPGA Linear interpolator, problem in difference terms

After re-thinking, I can pre-compute those values (they are just a few) and pass them as the slope of the linear interpolation. That would force me to work with fixed point arithmetic in the interpolator, right? Yes. I think there are two resource effective implementation variants of table interpolators. - Having equidistant 2^N +1

## help in programming of atmega 16

this time I am working on the a project for linear and circular interpolation. I am using atmega 16. I want to know that how will I feed the program in it. And before it how will I check my program whether it is right or not. I read about codevisionavr but didn't understand that which version should I use. Help me.

## logarithm unit implementaton

10 bit precission sounds really poor for double precision, but I don't know your specification. I assume that a hybrid strcucture, e.g. LUT with linear interpolation gives best resource utilization.

## Matlab code to Upsample a given sequence.

Hi, the upsampling is not that straight forward as down sampling. there are various methods to do the upsampling, the easiest in my opinion is linear interpolation, but you can use quadratic methods, cubic spline interpolation etc... depends on why you need it for... so you have to specify your application a bit more. would recommend you (...)

## 2 stage interpolated fir filter with pass band gain of 6.02 db

Hi all, I am designing a interpolated fir filter. I have designed FIR filter using the coefficients that I got from matlab. But how to design a 2 stage interpolated fir filter with pass-band gain of 6.02 db. I read many IFIR filters which uses linear interpolation/b spline interpolation. But I did not get any idea abt getting (...)

## to get .lib timing files for NLDM and CCS charac methods comparison (28nm ideally).

to complete the artmalik informations, the NLDM is only a table, and the interpolation is linear between each point define inside this table. In CCS, the model describe the wave form of the rise/fall delay (and other), then the calculated value is more accurate than the NLDM. There is a third model:ECSM, Effective Current Source Model is based

## Linear Interpolation in Hspice

I want to run multiple tests with different parameter each time in hspice. I did that using .alter command, but the problem is that it gives results in different files and not in one single file. Also after running these tests, i want to join the points using linear interpolation. Any idea how to do it in Hspice Regards Kumar

## Matlab interpolation problem

Greeting experts, I need your opinion on the following statements. In order to get the window for linear interpolation, I had the formula: p(t)=1-t/Ts where Ts, I took it as 5 since I sub sampled the original image 4 times. Then, I had my window from -Ts to +Ts i.e., and hence this is my frame. My question

## FMCW sweep duration vs FFT spectrum/distance resolution

Hello! Let's assume that we have simple FMCW distance measurement system with linear frequency sweep from F1 to F2. Sweep duration is T. ADC frequency is enough to digitize 128 points for each sweep duration T. Then we do some windowing and perform an FFT. For example 1024pt FFT (yes, i know about 128 points and interpolation, but it is from real

## Help me understand a linear interpolation problem

the term "interpolation" I cant understand clearly yet The term is introduced, and in my opinion basically explained in problem text. You have time discrete signal samples and want to design a time-continuous reconstruction of the original signal. linear interpolation is the simple method of connecting two point with a straight line

## FPGA: 2 ^ X, how do you do it?

My initial thoughts are to divide x down by 2 until it is on the range of . So you're computing y = (2^n)^m, where x = m*n and m is a power of 2, and n is on the range of . You can then do a LUT or a linear interpolation to compute v = 2^n. Take v and multiply it by itself m times. An example.. y = 2^5.6 y = (2^0.7)^8 y = (1.6224

## image resolutional enhancement

i need help to get mat lab code in interpolation techniques . nearest neighbour, bi linear,bi cubic , edge directional . atleast bicubic interpolation please its very need for my project.

## calculate for transistor s-parameter & circuit design

BFR92A has s-parameters upto 3GHz including 800MHZ and 900MHz. That's enough to design a low noise amplifier.S-parameters aren't changed very radically between two frequencies.A linear simulator will do a interpolation at a frequency which is not included in the list

## microstrip array simulation in hfss

whenever you want to find out the VSWR and S parameters its best to run interpolation the results are quick and accurate.once you know your VSWR and s parameters u can let the simulation run for linear count on discrete settings.

hi drawing a linear line between 2axis by controlling two motors.

Is the phase interpolation the function (1-a)*cos(2*pi*f*t)+a*sin(2*pi*f*t) where a defines the range of phase interpolation? This is obvious a multiplying function as seen in your lower schematic. But the inputs must be also be pure CW's. Otherwise the interpolation is not linear.

how can you compute fourier transform form Z-transform ? Why IIR filters doesnt have linear phase? Can IIR filters be linear phase? how to make it linear Phase? What is the advantage of a Direct form II FIR over fom I? Tell some thing about interpolation and decimation? What is interpolation (...)

## Linear interpolation algorithm

Hi there! I would have two questions to you. Lets talk about the first only!In my Electronics project i have to use linear interpolation.I found this document on the web: The problem is that after reading and trying to follow the equations i get confused. I think

## Should I interpolate ENR dB values?

Most probably linear interpolation is enough. But you may try second order too. You can see that the calibration data and decide how "smooth" it is.

## 120 dB DAC Design for audio

Hi, Has anybody built one of these 120 dB audio DAC? I have a question about it...... It typically has an interpolation filter and a DS modulator followed by an off-chip filter. Is the interpolation filter just a simple linear interpolator or does it require some complex interpolation algorithm? Colombo2

## Can you help me in use of the m/w/o

Hi, MWO doesn't allow EM structure optimisation (yet). You could try to use X-models for your discontinuities in the linear simulation (they are based on EM simulations and are the most accurate). Than you can tune and optimize them. You have to fill the EM interpolation tables previously for your substrate material. Or you can simulate your fi

## How does servo indexer work?

Hi guys, I searched how servo controllers work on web, and satisfied but i can't find information on linear interpolation and circular interpolaion. We use pid algorithms, motion profiles but are parameters in procedures (in motion control program) independent in linear and circular interpolation?

## help about lineer interpolation with servos

Hi All, I'm working on some servo mechanisms. I want to make a linear interpolation algorithm with micros (pic, x51, ti). I built a cnc with stepper motors. It has linear and circular interpolation but servos are different, i think... Please help, any documents acceptable.
