What is time reversal operation?
time reversal, in physics, mathematical operation of replacing the expression for time with its negative in formulas or equations so that they describe an event in which time runs backward or all the motions are reversed.
Why one signal is reversed in convolution?
But, if the sliding one is reversed, then you'll convolute the present time for both of them correctly. And that's why one function is reversed in convolution.
What is shifting operation in DSP?
Time shifting means, shifting of signals in the time domain. Mathematically, it can be written as. x(t)→y(t+k) This K value may be positive or it may be negative. According to the sign of k value, we have two types of shifting named as Right shifting and Left shifting.
What is time shifting of signals?
Time shifting or Shifting of a signal in time means that the signal may be either delayed in the time axis or advanced in the time axis.
