Question

Problem 3. Let $x(t)$ represent the signal shown in the following plot. The signal is zero outside the range $-2 < t < 2$. (a) Is this a continuous-time or discrete-time signal? (b) Write down $x(t)$ in the form of a piecewise function. (c) Plot $y_1(t) = x(t+1)$. Is it right shift or left shift? (d) Plot $y_2(t) = x(0.5t)$. Is it stretching or squeezing? (e) Plot $y_3(t) = x(0.5t + 0.5)$. Determine all values of $t$ for which $y_3(t) = 1$. (f) Plot $y_4(t) = x(-t)$ and even component $x_e(t) = frac{x(t)+y_4(t)}{2}$
