This circuit is a fourth-order low-pass filter with values for kHz. The values of Rv R2, C and C2, and R3, R4, C3 and C'4 can be scaled for operation at other. Draw the schematic diagram for the circuit to be analyzed. 3. A typical low-pass filter circuit, for example, might have a frequency response that looks like this:. Related Questions.

Median filter is quite effective in recovering the images confounded by salt and pepper noise. It discards outliers (impulses) effectively, but it fails to provide adequate smoothing for images corrupted with non-impulse noise. In this paper, two nonlinear techniques for image filtering, namely, New Filter I and New Filter II are proposed based on a nonlinear high-pass filter algorithm. New Fil...
