Hello Pablo,
Let's say you are trying to receive an FM signal centered around 100MHz. In
other words, the signal of interest is from
To continue: It is always easier to process signals in baseband (centered
around 0) than it is to process RF signals (due to the high sampling rates
required).
Given that the bandwidth you are interested in is in the order of 100kHz
(typical of FM radio signals), it is easy to see why radio

Hi Aditya, Hi Pablo,
the multiples-of-carrier-frequency problem is being solved in hardware
(you can't do this in software, since mixing is still analog domain).
Anyway, as Aditya explained, since you are processing baseband
signals, a lowpass is
