dsp.LowpassFilter provides the same advantages that dsp.FIRFilter provides in terms of fixed-point support, C code generation support, HDL code generation support, and ARM Cortex code generation support. Design a lowpass FIR filter for data sampled at 48 kHz. The passband-edge frequency is 8...
I am building a filter with Butterworth prototype and I do not know where I made a mistake. Apass = 0.6; % dB Astop = 16; % dB omega_pass = 1; Gstop = -16; omega_stop = 5; OMEGA = omega_stop/omega_pass; n = ceil( log10( (10^(-Gstop/10) - 1) / ( (10^(-Gpass/...
TheLowpass Filter Design in MATLABexample highlights some of the commonly used command-line tools in DSP System Toolbox to design lowpass filters. This example provides a more comprehensive overview of the design options available in the toolbox for designing lowpass filters. To begin with, this...

Consider a simple design of a lowpass filter with a cutoff frequency of 0.4*pi radians per sample: Fc = 0.4; N = 100; Hf = fdesign.lowpass('N,Fc',N,Fc); We can design this lowpass filter using the window method. For example, we can use a Hamming window or a Dolph-Chebyshev ...

In this paper a program developed in MATLAB programming language to aid in the design of all-pole active filters using operational amplifiers is presented. The filter structure chosen was the Sallen-Key that furnishes a filter with low sensitivity to element tolerances and it is easy to implement...
