In the specific band of frequencies their is no need to change the components in the circuit. It is known as:
- high pass filter
- low pass filter
- notch filter
- band pass filter
The Correct Option is D
Solution and Explanation
Top Questions on Filters
- A discrete linear time invariant system has an impulse response function given by \[ h[n] = \delta[n] + \frac{1}{2}\delta[n - 1] + \frac{1}{3}\delta[n - 2]. \] For input signal \( x[n] = \delta[n] + \delta[n - 1] \), which of the following option(s) is/are CORRECT for the output signal \( y[n] \)?
- Which one of the following represents the frequency response of a notch filter?
- A time domain signal is given by \[ x(t) = 20 \sin(100\pi t) + 36 \sin(150\pi t) - 2 \sin(300\pi t), \] where time \( t \) is in seconds. Among the following options, what is the frequency (in Hz) at which \( x(t) \) should be sampled for accurate signal reconstruction?
- A low pass filter with cutoff frequency of 250 Hz is NOT suitable for recording ________
- A signal is processed by a causal filter with transfer function \( G(s) \). For a distortion-free output signal waveform, \( G(s) \) must
