ripple filter

ripple filter

[′rip·əl ‚fil·tər]
(electronics)
A low-pass filter designed to reduce ripple while freely passing the direct current obtained from a rectifier or direct-current generator. Also known as smoothing circuit; smoothing filter.

If edge block, we apply a Modified Overshoot Ripple filter to the DCT coefficients.
They are (i) Measurement of ringing artifacts, (ii) Edge detection, (iii) Discrete Cosine Transform, (iv) Modified Overshoot Ripple filter, and (v) Exponential filter.
Modified Overshoot ripple filter is a low pass filter.
In general, [eta] should be below 0.2 to ensure the switching ripple filter effect.
Michael Short's work combines the shape of Canada's famous maple leaf with a ripple filter in Photoshop to produce a logo that is active and dynamic.
Initial values of capacitance are based on values for a Chebyshev 0.5 dB ripple filter. The number of filter elements was determined by the maximum length that the transmission line segments could be while remaining below a quarter wavelength at 26.5 GHz and by a division of the spacing between the diodes.
