What is shifting operation on signal?

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.

What is signal folding?

Folding transforms an operation from a unit-time processing to N unit-times processing where N is called folding factor. Therefore, multiple same operations (less than N) used in original system could be replaced with a signal operation block in transformed system.

What are the different types of operation performed on signals?

Addition, subtraction, multiplication, differentiation, and integration fall under the category of basic signal operations acting on the dependent variable.
