Radio transmitter incorporating digital modulator and circuitry to accommodate baseband processor with analog interface

摘要: A circuit provides a digital signal at optimal times to processor of transmitter. The includes complex analog-to-digital converter (ADC), demodulator and timing recovery circuit. ADC is connected receive an analog modulated baseband convert the signal. operates demodulate produce demodulated for input processor. receives control activates based on fixed relationship between receipt ADC.
