I have a question, how can i delay chirp signal? for example 6.5microsecond?
code:
% chirp signal generation 0-75 Hz ,7 chirp
clear all
clc
hchirp = dsp.Chirp('SweepDirection', 'unidirectional', 'TargetFrequency', 75, 'InitialFrequency', 0,...
'TargetTime', 1,'SweepTime', 1, 'SamplesPerFrame', 1176, 'SampleRate', 168);
figure(1);
plot(step(hchirp));
axis tight
xlabel('time (second)')
ylabel('signal amplitude')
% 6.5 microsecond signal delay.
hchirp_delayed=???
Thank you!

hello
you have to padd your signal with enough zeros to match the 6.5 microsecond signal delay (depends of your sampling frequency :
samples = round(6.5e-6/Fs);
