Question

why a crystal oscillator needs no tuned circuit

Answer 1

Answer:

because crystal oscillator is a good conduct of electricity

pls mark me as brainlist

Answer 2

A crystal oscillator needs no tuned circuit as crystal is already a tuned circuit.

• A crystal oscillator also an electronic oscillator majorly uses the resonance which is mechanical of a piezoelectric material, that vibrates crystal to create an accurate frequency electrical signal.
• The physical dimensions of the crystal are the basis for its resonance frequency; it also has robust physical properties, so it has a sharp Q and a low temperature drift.
