How to implement a frequency multiplier. How to create circuit designs in the GreenPAK Designer software. This article describes how to implement a frequency multiplier using a GreenPAK programmable ...

When designing bass reflex loudspeaker cabinets, it is necessary to measure the resonance of the speaker to an accuracy of about 1%. To do this, you need an audio oscillator and a frequency counter.

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.

Delay-locked loops (DLLs) are critical components in modern electronic systems, providing robust synchronisation of clock signals in a variety of applications ranging from high-speed communication to ...
