Introduction to DEMUX | Number System and Code | Digital Circuit Design in EXTC Engineering

## TL;DR

Demultiplexers have one input and multiple outputs, with the number of outputs determined by the select lines. Each output is activated based on the input condition.

## Key Insights

• 🔠 Demultiplexers have one input and multiple outputs, allowing for data distribution based on input conditions.
• 🫥 The number of outputs in a demultiplexer is determined by the select lines, which can be any power of two.
• ⌛ Only one output is activated at a time, based on the input condition.
• 😑 The expression for each output can be designed using logic gates.
• 📡 Demultiplexers can be used in various applications, such as data transmission and signal routing.
• 😑 Understanding the truth table and expressions for each output allows for effective demultiplexer design.
• 🫥 Select lines play a crucial role in determining which output is activated.

### Q: What are the main features of a demultiplexer?

The main features of a demultiplexer include having one input and multiple outputs, with the number of outputs determined by the select lines. Only one output is activated at a time based on the input conditions.

### Q: How can a demultiplexer be designed?

A demultiplexer can be designed by using logic gates. The expression for each output can be designed based on the select lines and the input condition using logic gates.

### Q: What is the purpose of select lines in a demultiplexer?

Select lines in a demultiplexer determine the number of outputs. The select lines help activate the corresponding output based on the input condition.

### Q: Can a demultiplexer have more than two select lines?

Yes, a demultiplexer can have more than two select lines. The number of select lines determines the number of outputs in a demultiplexer.

## Summary & Key Takeaways

• Demultiplexers have one input and multiple outputs, with the number of outputs determined by the select lines.

• Only one output is activated at a time based on the input conditions.

• The expression for each output can be designed using logic gates.
