Abstract
A digital data detecting apparatus comprises means for sampling an input digital signal at a frequency which is M times (M>1) higher than a channel bit rate, means responsive to two adjacent sampled values for computing an interval from a point where the digital signal intersects a reference level to a sampling time, and means responsive to an output from the computing means for generating a data detecting signal for detecting data of the digital signal.
Claims5
A digital data detecting apparatus comprising:
- (a) means for sampling an input digital signal at a frequency which is M times (M>1) higher than a channel bit rate;
- (b) means responsive to two adjacent sampled values for computing an interval from a point where said digital signal intersects a reference level to a sampling time;
- and
- (c) means responsive to an output from said computing means for generating a data detecting signal for detecting data of the digital signal.
