6.
A 4-bit ring counter is loaded with a single 1. The frequency of any given output is ________.
7.
Shifting a binary number to the left by one position is equivalent to ________.
Answer: Option
Explanation:
Shifting a binary number by one bit is equivalent to multiplying (when shifting to the left) or dividing (when shifting to the right) the number by 2.
8.
Assume a 4-bit Johnson counter is initially cleared. After the first clock pulse the output is 0001. After the next clock pulse the output will be ________.
9.
Assume a 4-bit parallel in/serial out shift register is loaded with a binary number. How many clock pulses are required after the parallel load has occurred before the first bit in the sequence appears on the serial output line?
10.
Assume an 8-bit serial in/parallel out shift register needs to be cleared but has no clear input. How many clock cycles are required before a zero applied to the input appears on the QH output?
