Angle Modulation Techniques
- Introduction to Angle Modulation and Bandwidth Requirement.
- Generation of Angle-Modulated Carrier—phase and Frequency Modulation for Narrowband (NB) and Wideband (WB).
- Reactance Modulator Circuits.
- Detection of Angle Modulation—slope Detector, Foster-Seeley Discriminator, Ratio Detector, Phase-locked Loop
We have seen earlier that for angle modulation the carrier signal, which is a pure sinusoid represented as Sc(t) = Ac sin (ωct + θ) with φ (t) = (ωct + θ) as the argument or angle, the instantaneous ...
