In processing the signal we experience aliasing, which
If f is the signal frequency having a noise of g (g>f) to avoid any kind of aliasing sampling frequency should be
(a)
What is the Nyquist theorem primarily concerned with?
The maximum frequency that can be accurately sampled.
The minimum amplitude required for signal detection.
The process of filtering out noise from a signal.
The relationship between frequency and time in signal processing.
Which of the following best describes oversampling?
Sampling at a rate significantly higher than the Nyquist rate.
Sampling at the exact Nyquist rate.
Sampling at a rate lower than the Nyquist rate.
Sampling only once per cycle of the signal.
What effect does low-pass filtering have on a signal?
It allows low-frequency signals to pass while attenuating high-frequency signals.
It amplifies high-frequency signals while reducing low-frequency signals.
It introduces noise into the signal.
It has no effect on the signal.
