The effect cannot precede the cause. The physical system, which satisfies the principle of causality, is said to be causal. More generally, we will call causal any func

Multiplication of the signal by a sliding window leads to short-time Fourier analysis and spectrogram. In the Wigner–Ville distribution, the time rev

Processes on digital signals can be achieved that are impossible for analog signals. In this chapter, we firs

We show that the function .. is an eigenfunction of a time-invariant digital system. The impulse response, the transfer function and the frequency response are defined.

We demonstrate the Shannon theorem, which sets the conditions for which sampling takes place without loss of information. We show the Whittaker–Shannon theorem proving that an analog signal can be reconstructed from its samples if the samplin

It follows that the impulse response of this filter is earlier. Since a minimum-phase causal filter has its zeros inside the unit circle, its inverse will be caus

These bases must also allow reconstructing the signal accurately and easily from the decomposition coefficients. It is known that the details of a signal are cont
