Spectral Analysis Of Pulse-Modulated Rf Signals
Pulse-modulated sinusoidal signal are the carrier frequency, the pulsewidth, the repetition frequency, and the number of pulses in or the duration of the signal. We use a Fourier series representation to show the influence of these parameters on the spectrum of a pulse-modulated signal at a microwave carrier frequency. When an ... Fetch Document

Chapter 8 Carrier Synchronization - NASA
(sinπfT/πfT)2, then direct modulation of the carrier with such a waveform would, for any modulation index β<π/2, result in a discrete carrier occurring at the point of maximum energy (i.e., f = 0) in the data modulation spectrum. This in turn makes it difficult to extract carrier synchronization from the discrete ... Retrieve Full Source
