Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...
Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...
Colorado Springs, Colo. — An RFID reader from Texas Instruments Inc. supports both amplitude- and phase-modulation receive modes. The TRF7960/7961 has several low-power modes to keep power dissipation ...
