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 ...

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 ...
