What is the process of modulation and demodulation?
Modulation and demodulation
Modulation is the process of encoding information in a transmitted signal, while demodulation is the process of extracting information from the transmitted signal. Many factors influence how faithfully the extracted information replicates the original input information.
How do you demodulate phase modulation?
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.
What are the two methods to demodulation?
Based on this nonlinearity, the demodulation methods can be broadly classified as methods using rectification (non-synchronous detection) and methods using mixing with a reference oscillator signal (synchronous detection).
Where modulation and demodulation is used?
The process of modulation is performed at transmission end of the communication system. Demodulation is performed at receiving end of the communication system. The electronic circuit that is required to perform modulation is called modulator.
