Explain how a phase-locked loop works with regards to FM demodulation.
1.) Angle Modulation can be subdivided into phase modulation (PM) and frequency modulation (FM). Highlight the differences between FM and PM. What is meant by the term instantaneous frequency? 2.) Describe what is meant by the term "Zero-Crossings" of a FM or PM wave. 3.) Is PM and/or FM a linear modulation technique? Explain. 4.) Describe one important advantage that angle modulation has over amplitude modulation. Describe one distinct disadvantage that angle modulation has over amplitude modulation. 5.) Describe the...
In frequency Modulation (FM), the instantaneous frequency of a
sinusoidal carrier wave will be modified proportionally to the
variation of amplitude of the message signal. Use Matlab to build
an FM modulation and demodulation process. The FM coefficient is
Kf=80, and the carrier frequency is 300Hz.
1. Generate a baseband signal as show below. Plot the baseband
signal in time domain and frequency domain. 2. Create an FM process and
plot the modulated signal in time and frequency domain.

Communication systemProblems A 25 MHz carrier is modulated by a 400 Hz audio sine wave If the carrier voltage 4 V and the maximum deviation is 10 KHz, write the equation of this modulated wave for FM. If the modulating frequency is now changed to 2 KHz, all else remaining constant, write the new equation for FM2. In an FM system, when the audio frequency (AF) is 500 Hz and the AF voltage is 2.4 V, the deviation is 4.8 KHz....
