RF and IF Amplifiershing network. The matching network is made to enable maximum power transfer of the receiving signal by equalizing the antenna impedance with the RF amplifier input impedance. After that, it is the job of the RF amplifier to increase the power of the received signal and prepare it for further process

Modulationor instance, while listening to a steady single-tone signal with constant amplitude and frequency coming out of a speaker, we merely receive the simplest message that conveys information only about the existence of the signal source and nothing else. If the source is turned off, then we cannot even

AM and FM Signal Demodulation carrier signal. This information recovery process is known as “demodulation” or “detection”. It is based on an underlying mechanism similar to the one used in mixers, where a non-linear element is used to multiply two waves and accomplish the frequency shifting. However, the demodulation process is
