Electronic Band Pass, Band Reject, Low Pass, High Pass Filter Symbol

In this article, we are going to see all types of electronic filter symbols. An electronic filter is a circuit or device that filters electrical or electronic signals. The main function of an electronic filter is to block the certain frequency signal and allow the certain frequency signals as per the design. Either they block the unwanted signal or bypass to the ground to filter an electronic signal. An electronic filter is also used to remove noise, distortion from a signal. There are different types of electronic filters as per their circuit design, applications, and frequency response.

Electronic Filter Symbol

Here, you can see the generic symbol of the electronic filter. The symbol is drawn by a line on the sine wave sign. In electronic circuit diagrams or single line diagrams, you can see these type of symbols.

High Pass Filter Symbol

High Pass Filter are those which allow the high-frequency signals through it and block the low-frequency signals. This type of electronic filters are used with communication circuits, signal receiver and signal transmitter circuits, audio processing circuits, etc. Here, you can see the symbol of High Pass Filter.

Low Pass Filter Symbol

Low Pass Filters are those which allow the low-frequency signals through it and block the high-frequency signals. this type of electronic filters are used with noise removal circuits, rectifier circuits, lighting circuits, etc. Here, you can see the symbol of Low Pass Filter.

Band Pass Filter Symbol

Band Pass electronic filters are those which allow the signal having a frequency within a certain range and block the signal having a frequency above or below that range. For, example a band pass filter has frequency range 10KHz -50KHz. So it will alow the signal having a frequency between that range, rest all the signal will be rejected or blocked. Here, you can see the symbol of Band Pass Filter

Band Reject Filter Symbol

Band Reject Filter or Band Stop Filters are those which block the signal having a frequency between a certain range set by the filter and allow rest of all the signals having frequencies above or below that frequency range. A band reject filter is just opposite to the bandpass filter. If a band-reject filter has frequency range 10KHz - 50KHz, then it will allow the signals having frequencies above or below that range. Here, you can see the symbol of Band Reject Filter.
