In this paper, we propose the sequential input of a noisy image patch and the impulse response of a low-pass filter (LPF) in the training of the conventional fast and flexible solution for CNN-based image denoising (FFDNet) architecture, which enhances denoising performance and edge...
The low‐pass filter has equally good frequency response characteristics and can be used to eliminate possible aliasing effects by ensuring that the signal to be sampled is limited in the spectral content. The impulse response of the sound field was calculated by using the proposed low‐pass anti...

I thought modeling the impulsresponse of (1/s) is another way to get the step function in the time domain And if you convolute the Stepfunction with the impulse response of the lowpass filter you would get the stepresponse of the lowpass filter Bu...
Design a minimum-order IIR lowpass filter with the same properties as the FIR lowpass filter. Change the FilterType property of the cloned filter to IIR. Get IIRLPF = clone(FIRLPF); IIRLPF.FilterType = 'IIR'; Plot the impulse response of the FIR lowpass filter. The zeroth-order coef...
Although a linear phase FIR, highpass filter can be designed in numerous ways, the result is invariably a filter with a very long impulse response. A straightforward approach to the design of a filter is to choose the ideal highpass filter as a starting point, (7.2)H(ejω)={0, ...
impulse response(IIR) filters could be designed in the CPU of the DSP chips,it will take CPU much time to run the IIR filters and thus the CPU will have no time to perform other system tasks such as communications and diagnostics.Based on these,a design of IIR low pass filter based on...
few dithered exposures are required to give perfect colour. The disadvantage is the slight smearing and loss of resolution caused by the AA filter, even when using Bayer Drizzle stacking. But maybe the sharp resolution can be restored by deconvolution with the impulse response of the AA filter?
