The threshold effect in demodulator is

  1. Exhibited by all demodulator, when the input signal to noise ratio is low.
  2. The rapid fall on output signal to noise ratio when the input signal to noise ratio fall below a particular value.
  3. The property exhibited by all A.M. suppressed carrier coherent demodulator.
  4. The property exhibited by correlation receiver.

B. The rapid fall on output signal to noise ratio when the input signal to noise ratio fall below a particular value...

 

When the value of the input signal to noise ratio falls below a particular value (called Threshold value), a rapid fall of the output signal to noise ratio is observed by the receiver…

This is known as the Threshold effect in demodulation....

The threshold effect occurs due to the presence of large noise in the modulated signal.…
