Which is problem of a demodulation?
The research showed that the major problems in the cause of these modulation and demodulation include electrical equipment interference, radio communication interference, weather/atmospheric interference, co-channel interference, impulse interference, near/far problem, ghosting, distorted “S” sound, twittering or ...
What is demodulation process of varying one or more properties of a periodic waveform?
In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal (high frequency signal), with a modulating signal that typically contains information to be transmitted.
Why must modulated signals be demodulated?
We modulate a high frequency signal to make it easier to launch our signal off of an antenna, then we demodulate in order to build easier circuits for the relatively low bandwidth modulating signal. CLICK Changing the coefficient in front of a sine wave is called amplitude modulation.
How do you demodulate a phase modulated signal?
A phase modulated signal of form x(t) can be demodulated by forming an analytic signal by applying Hilbert transform and then extracting the instantaneous phase.
