DEFINITION

Classification: 327/263

Delay interval set by rising or falling edge:

(under subclass 261) Subject matter wherein the delay time is determined by either (a) the interval between the occurrence of leading or trailing edges of a pulse signal or (b) the amount of time for the leading or trailing edge of a pulse waveform to rise or fall to a particular value.

2+, for phase characteristic selecting and particularly subclasses 3+ for phase angle sensing (e.g., lead/lag discriminators).

172+, for controlling the duration of pulse signals (e.g., pulse stretching) in pulse generators.
