Especially in the frequency bands below 1 GHz, you might find yourself interfacing with a module at really low level, where you might be tuning modulation parameters. The following overview should ...

One of the most common modulation examples is the aforementioned LFO, modulating the filter frequency or the oscillator pitch ...

So instead of PWM he decided to experiment with pulse density modulation. The idea is to ... With a PWM system, for example, if the time period is T, a 50% PWM drive would have the drive high ...

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...
