👉 In signal processing, a bandlimited function is a continuous-time function that has no frequency component above or below a certain limit. This means that it can be represented as a sum of a finite number of sinusoids with frequencies ranging from 0 Hz to some specified value (the Nyquist rate), and that the total energy is less than 1% of the original signal's energy. For example, consider a function f(t) that has a frequency component above 2 Hz. This function can
