Design a two bit down counter circuit that count from 11 to 00 – IGNOU MCA Assignment 2015 – 16

Design a two bit down counter circuit that count from 11 to 00. The initial state of the counter may be assumed to be 11. The counter will be in following successive states: 11, 10, 01, 00, 11, 10, 01, 00, 11 … Use any flip flop to design the circuit. You must design them… Read More »

Design and draw a 3 x 8 decoder using NOT gates and AND gates and explain its working. 8m Jun2007

Decoder converts one type of coded information to another form. A decoder has ‘n’ inputs and an enable line (a sort of selection line) and 2n output lines. Let us see diagram of 3×8 decoder which decodes a 3 bit information and there is only one output line which gets the value 1 or in… Read More »
