The Nyquist-Shannon sampling theorem is the fundamental principle that determines when signals should be sampled at a higher rate in digital systems. This theorem states that a signal must be sampled at a rate that is at least twice the highest frequency component of the signal (fmax) to avoid aliasing, which can lead to distorted … Read more
The steepness of the roll-off in a low-pass filter (LPF) is a crucial parameter that determines the filter’s ability to separate the desired signal from unwanted high-frequency components. As the order of the filter increases, the roll-off becomes steeper, providing better attenuation of the stopband frequencies. However, there are practical limits to how steep the … Read more
