Hi there,
I'm just approaching Simulink.
My aim is to build a filterbank which splits the audio imput signal into different frequency bands.
Specifically, I have a wave signal which is delivered through the block "From wave file" to 4 Biquad filters, with frequencies 1, 10, 100 and 1000. Between imput and filters I have an "Unbuffer block", because matlab says it is necessary to pass from frame based to sample based signal. Downstream the 4 filters there are 4 scopes.
The point is that I don't get anything from them but a very small transient when the imput audio finishes (!!). Personally I don't trust the need of using the buffer, which also makes the output become 3D. I must have messed up with something, but I can't see what. Any help??
S.
