help with ask demodulation

hi everyone i've written to perform modulation on train of rectangular pulses with a carrier. my rect pulses are uniform spaced 1e-6 apart with amplitude 1v. now i have to demodulate this ASK modulated signal. i have no idea about how to start about it?

any help or document with this is of great help

thanks

You may want to use a filter to filter out the carrier signal and extract the rect pulses from the mixed signal. Apply FFT and then IFFT.
