## PIC18f45k22 mikroC t type thermocoupler

I did that. Used x100 analog amplifier based on cheapest LM358. But the mathematic was a bit complex. Calibration needed with linear aqualization. Cold junction was fake - used 20 degrees (indoor use only).

## atan LUT vhdl from 1/8 quarter to full circle

atan function has some simple symmetry properties that helps you to make the table. Unfortunaterly an important relation isn't mentioned in the above wolfram link. But you should find it in any good mathematic handbook. Or e.g. at Wikipedia:

## How to implement spectrum sensing network in matlab?

I am currently working on cooperative spectrum sensing . i want to implement a network of secondary users in which two types of user presents, one is honest and remaining are malicious. they sense primary user signal and then take decision about its presence or absence and How can each user effect its neighbor? what would be the mathematical model

## FDTD convergence, FEKO

Hello dear guys and dear ladies; I am getting convergence error whil using FDTD method in FEKO. When I searched in the internet I reached very theoratical explanations and I am not numerical mathematic expert, just using FEKO. Can you explain me what is convergence in FDTD method ? Why may I be getting this error ? What can I do to prevent this

## Design Project (Digital Design Class)

The first thing I imagine is a FSM where in the first state you get the number, then in the second you do the operation and third you display the resul. On way to do it is by getting the complement of the number (e.g. 10010 --> 01101) and then add 1 to it (so the final result would be 01110). I'm sure there is a more complex mathematic procedure to

## Better formula to estimate energy output from a battery

It's quite simple mathematic in any case. But before you jump into conclusions, you should specify the load behaviour. You are assuming a constant P load. That's rather unlikely, except for a view electronic devices.

## Rogowski coil, hi voltage , pulse current measurement?

The mathematic can be found at Wikipedia Rogowski coils have no magnetic core. HV capability is a matter of insulation, which can be chosen according to your needs. Several application notes and basic literature can be found here See also:

## modeling music signal using harmonics filter bank

You are presenting a lot of mathematic expressions that you apparently don't fully understand. But you don't tell what you exactly want to achieve. E.g. what's the expected output of the signal analysis? Is it a "static" spectrum, or spectral distribution versus time (a spectrogram) or something else? In which regard do you want to model musica

## Suggestion of buying a calculator

Both 991ES and 991MS are good and perform all possible operations for Engineering mathematics. You have quite good advantages in 991ES. Its like you can view decimal point numbers in fractional form. eg: 1/2 instead of 0.5 This is a good advantage when u need final answers in fractional form. The above mentioned feature is not actually a di

## Multiparameter Simulation in Pspice, alternatives

Hello everybody, I'm simulating a circuit in Pspice. I need to optimize 2 different parameters in the same time and alsolink others to them trough a mathematic expression. The parametric AC simulation permits only to change one parameter or other Elemet values if theres a mathematic expression that links them to this Parameter. A nested

## Suggest a topic on RF circuit for analysis and mathematics simulation

Hi I would be glad if help me to find a good subject about RF circuit&System for analysis and simulation from mathematic base , for example volttra series analysis of power amplifier

## Anyone know and or using MALAGAL Software

It is " MMANA-GAL " and not Malagal. It is free software. And is used to analyze the design of an antenna using different mathematical processes. You can download it here: Download MMANA-GAL 1.2.0.20 Free - A program to analyze the desgin of an antenna using different mathematical proces

## a equation to demonstrate

hi: I have a mathematic equation 'A' to demonstrate: 1? + 3? + ...... + (2n+1)? = (n+1)(2n+1)(2n+3)/3 I have a known equation 'B': 1? + 2? + 3? + .... + n? = n(n+1)(2n+1) /6 how to use 'B' to demonstrate 'A' ?

## How to derive formulation of PML in this hyperbolic equation

Hello guys. I am looking for a way to derive a mathematic formulation of PML in the x direction for the hyperbolic equation: Ut + Ux + Uy =0 and for the hyperbolic system : Ut + AUx + BUy = 0 ; where A= B= [0 0 1; 0 0 0; 1 0 0

## HELP! mathematic expression in at89c51ed2

i have written a C code for my expression. but i am not sure if my MCU could run it or not... can my MCU support to do this mathematic expression? the C code goes like this... void EQUA (void) { for (x=0; x

## help on c programming in 8051 for mathematic expression

i want to programme a mathematic expression into a 8051... the expression is... y = 0.002151*exp(-((x-0.5624)/0.0253).^2) + 0.02408*exp(-((x-7.086)/6.804).^2) + 0.002172*exp(-((x+0.0006227)/0.08174).^2) + 0.0006227*exp(-((x-0.4409)/0.06945).^2) + 0.0009454*exp(-((x-0.2971)/0.1107).^2) + 0.0005545*exp(-((x-0.1982)/0.06293).^2) +
