### Educational Content on Edge-Triggered Registers

**Topic: Understanding Edge-Triggered Registers**

#### Problem Statement:
4. Assume you have an edge-triggered register with four bits. Fill out the output waveform data based on the clock (clk) and input data (D).

#### Diagram Explanation:

The diagram includes three waveforms:

1. **Clk (Clock) Waveform:**
   - A square waveform representing clock cycles with repeating rising and falling edges. The rising edge is crucial for this problem since it indicates when the register captures input data.

2. **D (Data) Waveform:**
   - A series of data values indicated by binary numbers, aligned with the clock waveform. The values at various segments are:
     - `1001`
     - `0010`
     - `1000`
     - `1111`
     - `0001`
     - `0111`
     - `0101`

3. **Q (Register Output) Waveform:**
   - Currently incomplete, this line needs to be filled in to represent how the register stores and outputs data after each rising clock edge.
   - In edge-triggered registers, the data is captured on the rising edge of the clock signal.

#### Solution Approach:

- At each rising edge of the clock, the data present in the D waveform at that moment will be captured and held by the Q output until the next rising edge.
- To complete the Q waveform, note down the values from the D waveform aligned with the rising edges of the Clk waveform:
  - First Rising Edge: `1001`
  - Second Rising Edge: `0010`
  - Third Rising Edge: `1000`
  - Fourth Rising Edge: `1111`
  - Fifth Rising Edge: `0001`
  - Sixth Rising Edge: `0111`

The Q waveform should be drawn with these captured values, remaining constant between rising edges.

### Summary:
This exercise demonstrates how an edge-triggered register works by capturing input data only on the rising edge of a clock signal, holding the value until the next rising edge. This behavior is foundational in digital electronics, enabling precise data synchronization in various circuits.
