The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

We recently saw how certain audio power amplifiers can be used as oscillators. This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...

Modulation is the process of imposing information contained in a lower-frequency electronic signal onto a higher-frequency signal. The higher-frequency signal is called the carrier and the ...

When modulation adds information to a carrier signal, it adjusts one of its qualities. Properties of carrier signals that modulation can alter include the following: Modulation also differs based on ...
