Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

The pace of the world of digital communications is increasing at a tremendous rate. Daily, the engineer is requested to compact more data in the same channel bandwidth with closer channel spacing. As ...

People often ask me to talk about the waveform distortion that can be introduced by filtering. Each time I sit down to write a Filter Wizard piece on this topic, I either get overwhelmed by the amount ...

The design of finite impulse response (FIR) filters remains a cornerstone of digital signal processing, with ongoing efforts to refine both the algorithmic and hardware aspects of their implementation ...

Abstract: Digital signal processing in continuous-time features some interesting properties with respect to very low power consumption and improved signal quality compared to classical discrete time ...

Finally, we perform a 1680-point inverse DFT on H(m) to obtain the interpolated h(k) impulse response (coefficients), shown in Figure 13–73(b), for our desired filter. (The ten-fold compression of the ...

Abstract: The proposed work presents a real-time hardware design for MRI and CT image denoising using a separable two-dimensional linear-phase FIR filter on a Xilinx Spartan-6 FPGA. Unlike ...
