hi,
I have two floating point arrays say
Signal1 = sin(2 * pi * 10 * (.1:.1:10));
Signal2 = sin(2 * pi * 5 * (.1:.1:10));
Now I want to covolve t...

Hi,
If you need a discrete linear filter,
all you need to do is implement the equation
a(1)*y(n) = b(1)*x(n) + b(2)*x(n-1) + ... +
b(nb+1)*x(n-nb) - a(2)*... 
Glen Ragan - Feb 27 2004
Yes, the filter() function will do filtering. Since you seem to be
doing signal detection, you would also be interested in convolution,
conv(), with the time-revers...

it sounds like a homework?

Glen Ragan - Aug 5 2003
You cannot convolve the two filters because their input rates are not
equal. You can:
1. Multiply the real-frequency responses together, H12(f) = H1(f)*H2(f)
= H1...
