**Topic: Demultiplexer Waveforms**

**Instruction:**
The data input waveform and data select waveforms in Figure 6-38 are applied to a demultiplexer with eight active-HIGH outputs. Show each output waveform in relation to the given waveforms.

**Figure 6-38 Explanation:**

The diagram illustrates a set of waveforms utilized in the operation of a demultiplexer. It includes one data input labeled as "Data input," along with three select inputs labeled \( S_0 \), \( S_1 \), and \( S_2 \). Each input displays a distinct rectangular waveform pattern.

1. **Select Inputs:**
   - **\( S_0 \):** Has a longer HIGH duration followed by a similar LOW duration.
   - **\( S_1 \):** Alternates between HIGH and LOW states, with each state lasting half the duration of the \( S_0 \) signal’s HIGH period.
   - **\( S_2 \):** Flips between HIGH and LOW even more rapidly than \( S_1 \), with each state lasting half the duration of the \( S_1 \) signal’s HIGH period.

2. **Data Input:**
   - Displays a waveform with intermittent transitions between HIGH and LOW states, forming a pattern that correlates with the select inputs.

**Objective:**
The task involves illustrating how each output of the demultiplexer reacts based on these input waveforms. The outputs will correspond to select input combinations driving the data input to different states.

**Learning Outcome:**
Understand how select input waveforms control a demultiplexer’s active-HIGH outputs, and visualize how data inputs are routed through specific channels as determined by the select signals.

---

This explanation helps demystify how select signals interact within digital circuits to route data accurately, a crucial concept for learners studying digital electronics.
