Class Information
Number: 330/125
Name: Amplifiers > With plural amplifier channels (e.g., parallel amplifier channels) > D.c. and a.c. amplifier channels
Description: Subject matter wherein at least one of the signal channels has a D.C. conductive path from source to load, or where branched channels are involved, from or to the common junction point of the channels to the separate loads or from the separate sources or between common junction points in parallel channels; and at least one other channel has its signal transmission path, as set forth above, involves coupling circuits which will conduct only A.C. signals, because of signal coupling by a series condenser or transformer, and which will not conduct D.C. in that signal channel circuit.
