Each stream has a sampling rate of fADC/M, where M is a positive integer greater than 1. After translation into M parallel streams of IF samples centered about an IF of fADC/4, they are demodulated by applying first coefficients to even IF samples to produce even demodulated samples and applying second coefficients to odd IF samples to produce odd demodulated samples. The even samples are filtered using first filter coefficients and the odd samples are filtered using second filter coefficients to produce a complex baseband signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency agile digital radio receiver","description":"In a digital receiver, an ADC converts an analog RF signal to a digital RF signal at a sample rate of fADC, which is converted into M parallel streams of RF samples.
