Study Notes
Binary Counter
- The count range of a binary counter with n bits is 2^n.
- The basic memory element used to build binary counters is a flip-flop.
- A binary counter increases its count by incrementing the previous count when the clock pulse is applied.
- Determining the count range is crucial in the design of a binary counter as it determines the maximum count a counter can store.
4-bit Binary Counter
- The count range of a 4-bit binary counter is 2^4, which is 0 to 15.
Multiplexer
- The primary function of a multiplexer in a digital logic circuit is to enable multiple signals to share the same output line.
- The data input to be routed to the output line in a multiplexer is determined by the select lines.
- Another name for a multiplexer is a data selector.
- The function of the select lines in a multiplexer is to select which input line is routed to the output line.
- The operation of a multiplexer is controlled by the selection of the input lines through the select lines.
