Positive feedback is used in oscillators to maintain running or oscillating. An oscillator is basically an amplifier which has a feedback path from the output back to the input. This allows a portion ...

This oscillator circuit permits crystals to be electronically switched by logic commands. The circuit is best understood by initially ignoring all crystals. Furthermore, assume that all diodes are ...

Of all the low-frequency oscillator configurations, the Wien Bridge has to be the friendliest and easiest to get along with. Like a faithful dog, it behaves itself regardless of the weather, is not ...

Just as most electronic products today contain at least one embedded controller, most also have at least one crystal oscillator. In fact, some multiprotocol networking and telecom equipment can ...
