**Problem 2 (Time-invariance).** Determine whether the following systems are time-invariant or time-varying. Note the first two are CT and the second two are DT.(a) \( y(t) = \sin(x(t)) \)(b) \( y(t) = t \sin(x(t)) \)(c) \( y[k] = 3(x[k] - x[k-2]) \)(d) \( y[k] = kx[k] \)---**Explanation:**- **Continuous-Time (CT) Systems:** Refers to systems with continuous input values over time. - (a) \( y(t) = \sin(x(t)) \) evaluates the sine of the continuous input \( x(t) \). - (b) \( y(t) = t \sin(x(t)) \) multiplies time \( t \) with \( \sin(x(t)) \), suggesting a dependency on time.- **Discrete-Time (DT) Systems:** Refers to systems with discrete input values at specific time intervals. - (c) \( y[k] = 3(x[k] - x[k-2]) \) processes two previous discrete-time inputs, weighted by a factor of 3. - (d) \( y[k] = kx[k] \) involves a multiplicative factor of the current index \( k \) with \( x[k] \).This problem explores the concepts of time invariance, identifying changes in output with shifts in input over time.
