Answer 2

Answer:

1. Oscillator:

The fundamental building block of all ac signal sources is an oscillator. It produces a sinusoidal signal with predetermined amplitude and frequency. One of the most fundamental and practical tools used in electrical and electronic measurements is the oscillator.

2. Amplifier:

The input signal is strengthened by an amplifier without the waveform or frequency changing. The external dc source provides the extra power that is needed. As a result, an amplifier can be thought of as an energy converter that converts energy from a dc source into ac energy at the signal frequency, with the input signal controlling the energy conversion process.

Explanation:

Here are the differences between an oscillator and an amplifier:-

• The oscillator is an electrical circuit that produces output without the application of input, whereas the amplifier produces output as an amplified form of input.
• Although the oscillator utilizes positive feedback, the amplifier mostly uses negative feedback.
• Although oscillators are designed to produce electronic signals, amplifiers themselves do not produce any signals.
• The oscillator functions as a source, while the amplifier acts as a multiplier.
• The oscillator receives the oscillatory signal from the amplifier, which then gives an amplified signal.
• The oscillator is the device that produces the periodic electronic signal; the amplifier does not.
• Oscillators emit a signal as soon as power is applied, but amplifiers wait until an input signal is delivered into the input before acting.
• The amplifier has an input, whereas oscillators only have an output.
• The phase difference between the input and output of an amplifier is typically 180 degrees, whereas that of an oscillator is 0 degrees or 360 degrees.

• While oscillator output frequency only depends on passive components, amplifier output frequency depends on both active and passive components.
