I have generated a Thrian fractional delay filter using (thiran function) in MATLAB
where 0.3 is the time delay and 1 is the sample time. The output is a discrete time transfer function, the generated filter is all-pass, infinite impulse response (IIR) filter.
The problem is that I could not apply it to a signal
x(t). So I would like to know how to filter a signal with the generated thiran filter in MATLAB, what should I use to filter a signal with thiran filter? I can generate thiran filter using (thiran) function and the result will be a discrete time tf, but how to use it to filter a signal. I have tried to use
tf functions but they all did not work:
conv functions did not work because they require polynomial coefficients or numerator and denominator coefficients
thiran function generates a discrete transfer function.
[num,den] = tf(d)
function did not work because it can only convert a filter transfer function which is configured by
designfilt function, so in this case
d cannot be a thiran filter,
d can only be configured by
