The image you uploaded shows exercises related to signal processing and unit step functions (Heaviside distributions). Specifically, there are two parts:

### Part I: 
It starts with a signal \( x(t) \) shown as a piecewise function that takes different values for different time intervals. The task is to:
- Determine and plot the graph of the expression:
\[
\frac{x(t) + x(2 - t)}{U(1 - t)}
\]
Where \( U(t) \) is the unit step function, or Heaviside function, defined as:
\[
U(t) = 
\begin{cases}
0 & \text{if } t < 0 \\
1 & \text{if } t \geq 0
\end{cases}
\]
You are asked to understand the combination of the signals \( x(t) \), its reflection or shift \( x(2 - t) \), and how these relate to the Heaviside step function.

### Part II:
It introduces a new signal \( h(t) \), which is piecewise and takes values between \( -2 \leq t \leq 2 \). The task is to determine and analyze signals involving combinations of \( h(t) \) and the unit step function \( U(t) \), such as:
\[
\frac{1}{2} h(t) U(t) + h(-t) U(t-1)
\]
There are also other expressions involving shifts and reflections of \( h(t) \).

### Next Steps:
I can assist you in solving these step-by-step by breaking down the operations, performing the transformations, and plotting the graphs.

Here are some related questions to help clarify these concepts:
1. How does the Heaviside unit step function \( U(t) \) modify the behavior of a signal when applied?
2. What is the effect of time-shifting a signal, e.g., \( x(2 - t) \), on the original signal \( x(t) \)?
3. Can you explain the difference between \( h(t) \) and \( h(-t) \) in terms of signal reflection?
4. How would you compute the convolution of two signals like \( x(t) \) and \( h(t) \)?
5. What properties of linearity and time-invariance are useful when analyzing these signal transformations?

### Tip:
When working with piecewise or unit step functions, always carefully evaluate at the boundaries where the function behavior changes (e.g., at \( t = 1 \) for \( U(1-t) \)).

Determine and analyze signal transformations involving Heaviside unit step functions (U(t)) and piecewise signals (x(t) and h(t)).

Explore signal transformations involving unit step functions and time-shifting in signals. Learn how to analyze and graph signal expressions like x(t) + x(2 - t) with Heaviside unit step functions. Ideal for undergraduate students studying electrical engineering or signal processing.
