Operations performed on signal

Explain the operations which are performed upon the signal?

E

Expert

Verified

Operations that are performed over the dependent variables:

a) Amplitude scaling: y (t) =cx (t), where c refers to the scaling factor, x(t) is known as the continuous time signal.

b) Addition: y (t) =x1(t) +x2(t)

c) Multiplication: y (t) =x1(t) x2(t)

d) Differentiation: y (t) =d/dt x (t)

e) Integration: (t) =∫x (t)dt

Operations which are performed over the independent variables:

a) Amplitude scaling

b) Time shifting

c) Time reversal
