Baseband Pulse and Digital Signaling

Baseband Pulse and Digital Signaling. Definitions. If bits are encoded into one symbol Baud Rate D = N/T o (# Symbols per unit of time) Bit Rate R = lD (# Bits per unit of time, assuming l bits per symbol) Also Baud Rate D = 1/T symbol (The frequency at which symbols are sent)

Chapter 4. Angle Modulation

Chapter 4. Angle Modulation. 4.4 Narrow-Band Frequency Modulation. We first consider the simple case of a single-tone modulation that produces a narrow-band FM wave We next consider the more general case also involving a single-tone modulation, but this time the FM wave is wide-band
