- Topic is about shift registers in electrical engineering. 1. What is the main functional purpose of a register? We are looking for the specifics of what a register does in isolation, not with respect to applications. 2. In what cases might we use serial and parallel inputs/outputs? 3. Describe the purpose of the debouncer in your own words. 4. Is an SN5474 the same as an SN 7474? If not, how do they differ?1. Assume that the registers are 8-bit wide.

- Design a four‐bit shift register with parallel load using D flip‐flops. There are two control inputs: shift and load. When shift = 1, the content of the register is shifted by one position. New data are transferred into the register when load = 1 and shift = 0. If both control inputs are equal to 0, the content of the register does not change.1) What is the biggest binary number (decimal value) you can write with 6 bits?
