Key Features



reduce the signal from the nearby transmitter close to a transmitter that it swamps all other signals. The Band Stop Filter is used to remove or greatly reduce the signal from the nearby transmitter
Reject attenuate a specific frequency Notch filters can be highly selective and can be designed to reject or attenuate a specific frequency or harmonic content generating electrical noise, such as mains hum within a circuit.
Protective assembly Prevents accidental de-tuning of precisely tuned resonant circuit

Introduce of Band Stop Filter

A band stop filter, also known as a notch filter, blocks and rejects frequencies between its two cutoff frequency points, passing all frequencies on either side of the range. By combining a basic RC low-pass filter with an RC high-pass filter, we can form a simple bandpass filter that will pass a frequency range or band on either side of the two cutoff frequency points. But we can also combine these low-pass and high-pass filter sections to produce another RC filter network called a bandstop filter, which blocks or at least severely attenuates the frequency band within these two cutoff frequency points.

A Band Stop Filter (BSF) is another frequency selective circuit that functions exactly the opposite of the Band Pass filter we saw earlier. A band stop filter, also known as a band stop filter, passes all frequencies but attenuates frequencies within the specified stop band considerably.

In signal processing, a band stop filter or band stop filter is a filter that keeps most frequencies constant but attenuates frequencies within a specific range to very low levels. [1] It is the opposite of a bandpass filter. A notch filter is a band stop filter with a narrow stop band (high Q factor).Contact us with your exact filter requirement & we will look at custom options for you.



Q.Could you supply the sample for me to test first?

A.We are honored to offer you samples. New clients are expected to pay for courier cost,we can make samples according to your need.
