Electronic Filter Technology

Design Electronic Filter CircuitsSome higher-end amplifiers have very high filtering requirements for the power supply of the front and receiver, and no hum can be heard from the speakers. Here is an electronic filter with simple circuit and excellent effect, which can achieve the purpose of almost

Circuit Design of Transistor Electronic FilterIn many electronic circuits, especially some small signal amplifying circuits, the power supply often adds a first-stage transistor electronic filter, and its circuit structure is shown in Figure J1. If the right side of the figure is an ordinary RC filt
