This m-file simulates the operation of the heterodyne section and
demodulating section of a garden variety AM receiver. An array is created
that represents the superposition of three separate RF carriers, each
modulated at a different audio frequency. This is the kind of signal that
could be expected at the output of the LNA. This signal is multiplied by
a local oscillator, passed though an IF filter, and demodulated using a
simple envelope detector (half-wave rectifier and single pole LPF). Some
plots are created at the end to show the signal at various locations in
the receiver.- This m-file simulates the operation of the heterodyne section and
