11. Counters and Registers - Part D
The chapter focuses on shift registers, highlighting their types, functionalities, and applications in digital electronics. It covers various configurations such as parallel-in parallel-out, bidirectional, and universal shift registers, alongside shift register counters, both ring and Johnson types. Additionally, it presents practical examples and discusses the IEEE/ANSI symbology for registers and counters.

What we have learnt
- Shift registers can operate in various configurations, each designed for specific data handling tasks.
- Shift register counters can create a defined sequence of states and include types like ring counters and Johnson counters.
- Standards like IEEE/ANSI provide a uniform way to represent the functionality of digital components in schematics.
Key Concepts
- -- Shift Register
- A storage device that moves data in and out sequentially; can operate in serial and parallel modes.
- -- Ring Counter
- A type of shift register counter where only one flip-flop is set at any time, and its output is fed back to the input.
- -- Johnson Counter
- A shift counter that performs a unique counting sequence using inverse feedback, effectively doubling the modulus.
- -- Universal Shift Register
- A versatile register capable of operating in multiple modes - such as serial or parallel input/output.
