Hello everyone! :)
So, I want to use a fractional delay filter to delay a signal for 0.075s. So I get a random matrix with an input of 1-10 signals. Signal:
x=0:0.2:pi;
s=sin(x);
To design a fraction delay filter with my requirements I use:
d = fdesign.fracdelay(0.075,'N',2);
hd = design(d,'lagrange','filterstructure','farrowfd')
My problem is to combine both of it, so my sine is delayed for 0.075s. So, does anyone have an idea how to solve the problem?
Kind regards Magnus354

Try this
delayed_s=filter(hd,s);
