This section is a collection of articles related to DC Machine and will cover topics related to DC Machine.This section deals with all the basics which forms the foundation of the Electrical Engineering.It consists of two shift right registers A and B, which stores the number to be added serially.
Bit Serial Adder Full Adder AddsFull Adder adds the one pair of bits and carry input at a time. A D-flip flop is used to store the carry output of the full adder and output of the D-flip flop is connected to the carry input of the full adder. While the carry output from full adder is transferred to the D flip-flop and its output drives the carry input of the adder. Let the number (AAAA) be 0111 and number(BBBB) be 0010, stored in shift registers A and B respectively. When the first clock pulse occurs, the values present in A and B registers shift from left to right by one bit. In addition to this, the sum is transferred to the S of the Sum Register and the Cout is transferred to the D flip-flop and its output becomes 0. When the second clock pulse occurs,the values present in A and B registers shift from left to right by one bit. In addition to this, the sum is transferred to the S of the Sum Register and the Cout is transferred to the D flip-flop and its output becomes 1. When the third clock pulse occurs,the values present in A and B registers shift from left to right by one bit. When the fourth clock pulse occurs, it transfers the S1 to S of the Sum Register. At the end of the fourth clock pulse, the sum value is (1001) will be available in the sum register and Cout is 0.
