To implement amplitude modulation (AM), we’d apply the modulating signal as a(t) and set Θ(t) to zero. Similarly, a phase-modulated (PM) signal would have a(t) set to a constant and the modulating ...

A block diagram of the Class-D amplifier is shown in Figure 1. The techniques discussed in this paper describe how a single-frequency, sine wave signal was generated through a Class-D amplifier with ...

Pulse-width modulation ... Fig. 1 shows a representative block diagram. ... wondering if there are other mixed-signal jobs the PWM peripheral can perform. The answer is, of course, ...

However, if the carrier and modulating signals interchange their entry port at the comparator input, equivalent to using the complement of modulated output, those terminologies may become blurred. 4.
