Homodyne reception
Web4 jun. 2024 · A homodyne receiver (and transmitter) uses only one frequency to move up and down the signal, as opposed to a heterodyne, which uses an intermediate … WebThe homodyne radio receiving apparatus includes an antenna, an antenna by-pass filter, an RF amplifier and a quadrature downconverter. The quadrature downconverter for the complex base band is centered around a desired reception frequency so that the complex baseband signals lie around zero frequency.
