Test Preparation

We see definition of Modulation in time and frequency domain, different types of Modulation, need for Modulation and lastly basic terminologies and notations used.

Introduction to Analog Modulation

We see the definition of amplitude Modulation, time domain representation, Modulation index:meaning and different formulas related to it. Lastly frequency domain representation.

Amplitude Modulation: Time and Frequency Domain Representation

This video discusses on multi-tone amplitude Modulation and its time and frequency domain representation. Lastly we discuss on bandwidth.

Multi-Tone Modulation, Time and Frequency Domain Representation and Bandwidth

Here we see basics of power calculation, importance of RMS value , deriving equations for power calculations of carrier, USB and LSB.

Power Calculations

In this video we see Modulation index for multi-tone amplitude Modulation,Power calculation for multi-tone Modulation, 
constrain on Modulation index and current relation in amplitude Modulation

Modulation Index, Power for Multi-Tone Modulation, Current Relation

Modulators, Demodulators (envelop detector ) , certain conditions on envelope detectors and errors that we see in envelope detector.

Amplitude Modulation: Modulators and Demodulators
