Businesses allocate resources for their best and most productive uses. the more a resource, the more costly it will be. a manufacturer that requires scarce and costly resources is likely to charge for its products.

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.

The most accurate readings that you can take on an analog vom are when the meter's pointer is at the a. center scale. b. extreme right. c. near right. d. extreme left.
