Question

Effect of frequency and phase error in synchronous detection

Answer 1

Explanation:

) Explain synchronous detection method of AM signals. Also

explain the effect of frequency and phase error?

Answer 2

Concept introduction:

The quantity of pulses that pass a set location in a predetermined period of time is known as frequency. Therefore, if a wave passes through in a half second, the frequency is $2$ per second.

Explanation:

We have to answer the effect of frequency and phase error in synchronous detection.

A question related to this has been given to us.

In this expression, φ represents the phase error and the amplitude of the demodulated output is maximum and equal to $(1/2) Ec$ when φ =$0o$ and the amplitude is zero when φ $= 90$ . This effect is called as the quadrature null effect of the coherent detector .

Final answer:

The final answer of the question is there is some effect and the effect is called as quadrature null effect.
