Types of Modulation : Analog And Digital Modulation

Modulation is a term that is going to be used very frequently in this book. So much in fact, that we could almost have renamed this book Principles of Modulation, without having to delete too many chapters. So, the logical question arises: What exactly is modulation The signal modulation decreases for smaller pitches. Because of the Gaussian intensity profile of the laser beam even pitches smaller than 12μm (fields of 6μm) can be detected easily with the 10μm laser.. Modulation and Radio Building Blocks.
