Multiplier circuit measures real power in high-frequency PWMs

Applications which require the precise monitoring or regulation of dissipated load power, such as motors or servos, can make use of a circuit that measures real power by finding the product of the ...

Two-IC circuit combines digital and analog signals to make multiplier circuit

The circuits presented here use ananalog switch—such as a DG419or one-third of a CD4053—to combinean analog signal with a standard PWMsignal. Most microcontrollers can easilygenerate the PWM signal.
