*Multiple options can be correct
Bipolar Junction Transistor MSQ - Question 1

Consider the following statements about an oscillator and choose which of them are true. An oscillator

Detailed Solution for Bipolar Junction Transistor MSQ - Question 1

An oscillator is a system consisting of active and passive circuit elements to produce a sinusoidal or other respective waveforms at the output without the amplification of an external source (signal). It transforms the dc power from the source to the ac power in the load.
This consists of a positive feedback amplifier and has noise as the initial signal and consists of a frequency signal selector.
The correct answers are: consists of a positive feedback amplifier, has noise as the initial signal, consists of a frequency selecting network
