Testing FIR filter design

Started by faz June 2, 2008
Hai,

To test and verify the FIR filter Wat r all the test inputs as samples
x(n) ....i can apply in addition to the following:
Impulse,step,sine,triangular,sawtooth,rectangular pulse,gaussian white
noise..

1.whether the above test generation signals are sufficient??
2.r still i have to add more???
3.wat r the other corner test cases??

regards,
faz

Hi Mikolaj, How does one verify apple?? Maybe Newton used Gravity to Verify Falling Apple.... or was is vice-versa?? And as someone rightly said: An apple a day keeps the the doctor away and if the doctor is beautiful you should keep the apple away....

what is this? some kinda insider point? or inside joke? i test FIRs by using MATLAB or Octave to FFT the impulse response to make sure the frequency response is what i was aiming for. if you mean testing the real-time computation, then i dunno what the answer is. general FIRs are pretty simple and straight-forward. ("fast convolution" ain't so simple.) it's pretty easy to calculate what the largest possible output sample could be, so you can have an idea for how to scale your FIR coefs. r b-j

It seems you would be able to verify an apple.
Let's wait till tomorrow. Let's wait for 'faz'.
If he would manage to verify an apple
he would be able to verify enything.
He even would be able to verify such words as:
to verify, optimal, best, how and why.

Nah, probably frustration or something like that. This guy 'faz' has asked the same question with minor variations for a few days now, without showing evidence that he actually contemplates the responses. Rune
Can u please make a comment on watever work i am doing and suggest for
the same...

I am helpless i am unable to get proper answer i even tried books and
various resources

Step by step. How would you verify an apple?
I am already confused and i dont know wat your r trying to explain
here..
