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

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

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.

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.

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.

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.

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 (...)

I am designing a interpolated fir filter. I have designed FIR filter using the coefficients that I got from matlab.

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

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

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

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

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

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

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

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.

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**.

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.

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?

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

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**?

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.
