After two downconversions in the receive path, the baseband signal must be detected. As explained earlier in Chapter 2, the baseband signals can be demodulated in either the digital or the analog domain. Accompanied by interferers in both cases, the desired signal must be applied to a channel-select filter. For analog detection, the filter must be designed such that the demodulator can detect the signal in the presence of interferers.
