DEFINITION

Classification: 327/165

Regenerating or restoring rectangular (e.g., clock, etc.) or pulse waveform:

(under subclass 100) Subject matter wherein a pulse waveform which has undergone attenuation or deformation is modified into an output pulse wave form whose characteristics correspond to an original pulse waveform prior to such attenuation or deformation.

(1) Note. Usually a feedback or regenerative system is utilized to reshape the distorted pulse wave form.
