Question:medium

An RC high-pass filter has \(R=10\,\text{k}\Omega\) and \(C=0.01\,\mu\text{F}\). The cut-off frequency is

Show Hint

The cut-off frequency of an RC filter is \[ \boxed{ f_c=\frac{1}{2\pi RC} } \] where \(R\) is in ohms and \(C\) is in farads.

Signals and their Fourier Transforms are given in the table below. Match LIST-I with LIST-II and choose the correct answer.

LIST-I	LIST-II
A. \( e^{-at}u(t), a>0 \)	I. \( \pi[\delta(\omega - \omega_0) + \delta(\omega + \omega_0)] \)
B. \( \cos \omega_0 t \)	II. \( \frac{1}{j\omega + a} \)
C. \( \sin \omega_0 t \)	III. \( \frac{1}{(j\omega + a)^2} \)
D. \( te^{-at}u(t), a>0 \)	IV. \( -j\pi[\delta(\omega - \omega_0) - \delta(\omega + \omega_0)] \)
