What is a Band Stop Filter : Design & Its Characteristics

December 14, 2020 By WatElectronics

Band Stop Filter

The band stop filter is a type of frequency selective circuit, that works exactly opposite to the bandpass filter. The name itself shows that it stops or rejects the particular range of frequencies of a signal. This filter is designed with the low pass filter and high pass filter, which are connected in parallel to allow high and low-frequency components. The band stop filter allows frequency components below the cut-off frequency and above the cut-off frequency. The cut-off frequency of the low … [Read more...]

BPF - Band Pass Filter

During signal processing, a device called a Band Pass Filter or BPF is needed to allow a particular range of required frequencies and to avoid unwanted frequency ranges or components. By this filtering noise signal can be reduced by eliminating frequencies that are not required. Different types of filters like linear and nonlinear, analog, digital, active and passive, etc. are available to use based on the requirement. This article discusses an overview of Band Pass Filter. What is Band Pass … [Read more...]

What is a Low Pass Filter : Circuit & Its Working

August 10, 2020 By WatElectronics

Low Pass Filter Circuit Diagram

In electronic devices, the filters are the circuits that allow desires frequency components and blocks all other frequency components of a signal. For example, in radio or tv, a tuning filter circuit rejects unwanted frequencies by allowing only the desired channel. Filter circuits are divided into four types based on the range of frequencies that the circuit would allow while blocking all other frequencies. They are low pass filters, high pass filters, bandpass filters, and bandstop filters. … [Read more...]

What is High Pass Filter : Working & Its Applications

August 7, 2020 By WatElectronics

High Pass Filter

Filters are the electronic circuits that allow particular frequency components and attenuate the unwanted frequency components of an input signal. These are found in various electronic applications to allow a particular range of frequencies of a signal. Basically, filters are divided into two types based on the type of components used in designing and operation. They are Passive filters and Active filters. Depending upon the range of frequencies, filters are categorized into 4 types. They are … [Read more...]
