Definitions
- the shift register 720 compares the offset delay clock signal 720 with the digital signal and generates a detected code.
- the outputs of shift register 548 are fed into majority detector 550.
- the first 902 and seventh 904 outputs are not connected.
- the last output 712 is provided as raw data to the 3V and 5V interfaces (FIG. 4D) .
- Majority pulse detector 550 receives the coded signals from shift register 548 and produces an accepted code signal as output when the majority of the outputs 906, 908, 910, 912 and 914 of shift register 548 are high. That is, a positive output will result when the majority of oscillator start times is ahead of the nominal start time and thus, a carrier is present.
- Output 560 of majority detector 550 is input into
