Z-transform properties 7. CTFT pairs 8. CTFT properties 9. DTFT pairs 10. DTFT properties 11. Fourier series 12. Sampling Only Important Formulas Covered

4. Continuous Time Signals and System Causality If the impulse response of system h(t) 0 for t<0 > If output y(t) depends only on past or present values of x(t) Stability h(t) < oo -00 BIBO: If for any finite input x (t), output y (t) is also finite.

5. Periodicity > If x(t + T) = x(t) ; Tols the time period. If time period of x1(t) and x2(t) be T,and T2 respectively, Then signal y(t) = Axl (t) + BX2(t) is periodic if T1/T2is a rational number and its time period is T = LCM (T1,T2) Convolution y(t) = x(t) * h(t) = | x(t) h(t-t) dt -00

6. Unit impulse function 8 (t) x(t) (t), x(0)6(t) x(t) * (t) x(t) x(t) * (t-to-x(t-to)

7. Unit step function t>0 t<0 not defined t- 0 u(t) -0 u(t) x(t) t0 t<0 t=0 x(t)u(t)0 not defined (t) * u(t 00
