I used the Matlab Filter Designer (Previously FDA Tool) to design a Low Pass Filter which allows frequencies till 75kHz and stops frequencies greater than 125kHz. It is a 31 Order Filter. Sampling ...

This project will walk you through the importance of Fast Fourier Transform (FFT) which is one of the major computation techniques in the world of Digital Signal Processing (DSP). It also explains how ...

Abstract: In this paper, the variation of gain vs frequency of analog low pass filter in the atmospheric environment, electromagnetic environment, and electromagnetic shielded environment are compared ...

The circuit was designed with the combination of high pass filter and low pass filter to create a notch filter circuit. High Pass Filter – an electronic circuit that allows the passage of high ...

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...

My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...

Abstract: A miniaturized broad-stopband helical cavity low-pass filter is proposed in this article. The filter is composed primarily of a helical transmission line and a SIR-like structure with two ...
