Class Information
Number: 326/30
Name: Electronic digital logic circuitry > Signal sensitivity or transmission integrity > Bus or line termination (e.g., clamping, impedance matching, etc.)
Description: Subject matter having a circuit to preclude signal or transmission deterioration by (a) using an impedance element to eliminate the reflective wave energy caused by impedance differences between the network and a connected circuit or (b) using a diode circuit to clamp or to clip the reflective wave riding on the top of an incident wave.
