Question
Assume the following block diagram for the entire exam.

The block diagram presented consists of the following components:

1. **Input Signal, \( R[a] \):** This is the initial input to the system, denoted as \( R[a] \).

2. **Summing Junction (\( \Sigma \)):** This component adds the input signal \( R[a] \) with the feedback from the output. The output of this summation is \( E[a] \).

3. **Block \( G_c[a] \):** This block processes the \( E[a] \) signal. It represents a transfer function or processing element in the system.

4. **Block \( G[a] \):** The output from \( G_c[a] \) feeds into this block, which applies further processing.

5. **Output Signal, \( Y[a] \):** The final output after passing through \( G[a] \) is \( Y[a] \).

6. **Feedback Loop:** A feedback loop is present, taking the output \( Y[a] \) back into the summing junction \( \Sigma \).

This block diagram is likely used to represent a control system or signal processing setup, focusing on feedback and system responses to inputs.
