Explain BCD to Decimal Decoder (3marks)<br />
Answer: (Page 163) Lec17<br />
"The operation of the BCD-to-Decimal Decoder is the same as a Binary 4-to-16 decoder, the only difference<br />
being that the BCD-to-Decimal Decoder has ten output pins instead of sixteen and the input is a valid BCD<br />
number. Thus invalid BCD codes 1010, 1011, 1100, 1101, 1110 and 1111 applied at the input of the Decoder<br />
do not activate any of the ten outputs."<br />
