책 : Discrete Time Signal Processing 3rd Edition - Alan V. Oppenheim, Ronald W. Schafer impulse function = delta function = unit impulse (δ[n]) δ[n] = 1 (n=0) unit step은 impulse function의 합 (-무한대 ~ n) (u[n]) u[n] = 1 (n>=0) discrete signal : sequence of numbers sample : individual signal value at an index real exponential : x[n] = Aa^n sinusoidal : x[n] = cos(w0n+Φ) Properties of unit impulse (d[..
