Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

This article investigates the demodulation capabilities of a DSSSsuper-regenerative receiver. Starting from the general expressionthat characterizes the receiver's behavior, we demonstrate that afew ...

Binary FSK(Frequency Shift Keying) and PSK(Phase Shift keying) are extensively used in telecommunication for digital data transmission. FSK/PSK modulator circuits usually employ analogue components ...

Signal modulation is one of the most basic and important concepts in the RF industry. It consists of using the variation of one or more parameters of a carrier signal to transmit information, ...
