Study Notes
Flip Flops
- SR (Set-Reset) flip flops have two inputs that control the state of the output; they can set, reset, or maintain the output state.
- JK flip flops improve upon SR by having a toggle function, allowing for more versatile memory storage.
- D type flip flops capture the value on the data input (D) at a specific time, usually on the edge of a clock signal.
- Edge triggering refers to the action that occurs at the rising or falling edge of the clock signal, ensuring synchronized operation and reducing glitches.
- Flip flops are used in digital circuits for data storage, registers, counters, and memory devices.
Registers
- Shift registers can shift data in or out, either serially or parallelly, facilitating data manipulation.
- A serial to parallel converter transforms incoming serial data into a parallel format for easier processing and access.
- A parallel to serial converter takes multiple data bits and transmits them sequentially, enhancing communication efficiency.
Counters
- Asynchronous up counters increment the value with each clock pulse without a common clock signal, leading to potential timing issues due to propagation delay.
- Synchronous down counters decrement the value simultaneously on each clock pulse, providing consistent timing across all bits.
- Decade counters count from 0 to 9 and then reset to 0, often used in digital clocks and frequency dividers.
