A crystal oscillator is basically a tuned oscillator. It uses a piezoelectric crystal as a resonant tank circuits. It is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. The
There are some important applications of electrolytic capacitor are as given below: The electrolytic capacitor is used for storage energy. It is used in biasing circuits. It is used in motor as start capacitor and run capacitor.
