Title: Eliminating band-pass filters from two tone binary data receivers
Inventor: MARTINEZ JOHN PETER
IPC: H04L27/152
Filed: 1992-07-08
Abstract: A data transmission receiver in which band pass filters are eliminated, the function of a band pass filter being carried out by two low pass filters with an equivalent specification. The received signal is split into two identical paths, each path comprising:-     1. A frequency-changer 11 and 12 which changes the frequency of the incoming signal down to a near- zero intermediate frequency. 2. A low-pass filter 13, 14 which will pass signals from DC (zero frequency) up to half the shift-frequency. 3. A high gain amplifier 15, 16 with a limited output. The output of a local oscillator 17 is fed to a phase shift device 1850 that local oscillator signals to the two frequency-changers are formed in such a way that one leads the other in phase by 90-degrees, resulting in a 90-degree phase difference between the intermediate frequency signals in each path, thus permitting resolution of ambiguity between reception of signals above and below the centre frequency.   <IMAGE>
