Simple MATLAB Simulation

Just follow the steps in this tutorial: http://appliedelectronicsengineering.blogspot.co.ke/2014/05/double-superheterodyne-rf-receiver.html#

Then do the following exercise:

Exercise :
1. Implement the steps outlined and carry out the simulation.
2. Repeat the steps for the following specifications:

o Input carrier frequency varies from 550 kHz – 1700 kHz
o Intermediate frequency of 455 kHz
o Receiver sensitivity remains unchanged at 1 μV

You may modify the design specifications for the various components as desired. Also
produce output waveforms for at least two carrier frequencies. attached document, and provide me with the matlab files for the requirement at the end of the file.

Thank you.
