How can we scale and delay a signal using convolution in Matlab? Plz help

Answer 1

[Image Analyst]

How about this for scaling:

signal = randi(9, 1,10)
amplificationFactor = 10;
scaledSignal = conv(signal, amplificationFactor)

and this for delay:

delayKernel = [ 0 0 1]; % 1 must not be the center element.
delayedSignal = conv(signal, delayKernel, 'same')

because this might be homework, I'm going to let you combine them.

thankyou v much

[Sri Harsha Palepu]

what is delay kernal

[Image Analyst]

It's the kernel (filter window weights) that will shift the signal by one element.
