Abstract

The universal widespread use of computers and the digital processing caused a kind of mental shift among some of specialist users. Charmed with unlimited might of Computer in its digital Virtual World, they overlooked the every non-digital means out of the computer. The channel of connection with external Real World also was ignored. Meanwhile very often just the parameters of this analog channel determine the resultant accuracy of the computer operation. This phenomenon is especially important when the system employs in the area lying out of commercial communications (the instrumentation, automation, control etc.). Note, that in this case the suppression of the interference is one of the most important problems. High order ARC-filter, which is built upon only one operational amplifier (single Op-Amp High-Order ARC-Filter) is more convenient in this condition. Some of special realizations and applications of ARC-circuits are considered below. The goal of this work is to attract the attention to the capabilities of ARC-circuits and to determine their “technological niche” in electronics.

Keywords: ARC-circuits, Filter, High-Order, Non-commercial-employment, Special, Single-Op-Amp.
