Abstract

The invention provides an electronic communication filter, comprising a first resistor to a seventh resistor, a first capacitor to a third capacitor, a first operational amplifier and a second operational amplifier. A signal is separately filtered by the second capacitor and the first capacitor doubly after being input through the first resistor in a steady flow mode, the filtered signal is divided into two paths, and then the two paths are combined to be input to the second operational amplifier, the first operational amplifier amplifies one path of signal, the signal is re-filtered by the third capacitor while being amplified through the second operational amplifier, and thus interference signals can be effectively filtered, and meanwhile, the signal also can be amplified, and the signalcommunication quality of the applied electronic communication equipment can be improved. Compared with the prior art, the electronic communication filter provided by the invention is adapted to the electronic communication equipment, ensures that the signal can be doubly amplified and the signal strength can be effectively improved; and meanwhile, the signal also can be subjected to triple filtering, the interference signals can be effectively isolated, the signal transmission quality can be improved, and promotion and use values can be obtained.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic communication filter. Background technique [0002] Filters, as the name suggests, are devices that filter waves. "Wave" is a very broad physical concept. In the field of electronic technology, "wave" is narrowly limited to the process of describing the fluctuation of the value of various physical quantities with time. This process is converted into a time function of voltage or current through the action of various sensors, which is called the time waveform of various physical quantities, or called a signal. However, electronic signals are susceptible to various interferences in the process of communication transmission, especially wireless communication, where the signal is greatly weakened. Therefore, in order to improve the quality of communication, continuous improvement and innovation are required. Contents of the invention [0003] The object of the p...
