Radio Frequency Modulation Made Easy
Modulation is a technique that changes the characteristics of the carrier frequency in accordance to the input signal . Figure 1.1 shows the conceptual block diagram of a modern wireless communication system. As shown in the figure, modulation is performed at the transmit side and demodulation is performed at...
Pulse Modulation
Publisher’s Note: To complement Dr. Saleh Faruque’s feature story providing an introduction to RF modulation, as well as Casey Spencer’s feature, Teslapathic, which employs pulse position modulation (PPM), we dug into our archives at Popular Electronics and discovered this terrific introduction to pulse modulation, of which PPM is a variant....
