B) Explore other digital circuits
Now that we have a solid understanding of adders, let's explore other digital circuits:
1. Subtractor:
A subtractor is a digital circuit that subtracts two binary numbers.
Requirements:
- Two input bits: A (minuend) and B (subtrahend)
- Two output bits: Difference (D) and Borrow (B)
Circuit Design:
We can use a similar approach to the adder, but with some modifications.
2. Multiplier:
A multiplier is a digital circuit that multiplies two binary numbers.
Requirements:
- Two input bits: A and B
- Four output bits: Product (P)
Circuit Design:
We can use a combination of AND gates and adders to implement the multiplier.
Other Digital Circuits:
- Encoder: Converts decimal to binary
- Decoder: Converts binary to decimal
- Multiplexer: Selects one of many inputs
- Demultiplexer: Distributes an input to many outputs
