low pass filter

An ideal low pass filter has frequency response given by H(jω) = {1, |ω| ≤ 200π {0, otherwise Let h(t) be its time domain representation. Then h(0) = ________ (round off to the nea...

A signal $$x(t) = 2\cos (180\pi t)\cos (60\pi t)$$ is sampled at 200 Hz and then passed through an ideal low pass filter having cut-off frequency of 100 Hz. The maximum frequency p...

A first order, low pass filter is given with $$R = 50\,\,\Omega $$ and $$C$$ $$ = 5\mu F.$$ What is the frequency at which the gain of the voltage transfer function of the filter i...

An analog electronic circuit that measures $$rms$$ value of the input voltage by averaging the square of the instantaneous voltage level, responds slowly to changes in the input si...
