Q- Calculate the efficiency of BCD codes wrt Binary number representation for (a) 4-bit (b) 8-bit. Ans: (a) With 4-bits we have 10 numbers represented in BCD while 16 in Binary hence Efficiency = (10/16)* 100 = 62.5% (b) With 8-bits we have 100(102) numbers represented in BCD while 256(28) in Binary hence Efficiency = (100/256)* 100 […]
