What is meant by BCD ripple counter?

binary coded decimal counter with carry propagated bit to bit by ripple method instead of carry lookahead combinatorial logic method. this is easy to build but has long settling time with invalid codes occurring before it settles. for example these counters will generate a 1010 code between 1001 and 0000.

What is bcd to gray code converter?

A BCD to Gray code converter is a digital circuit that converts Binary Coded Decimal (BCD) input to Gray code output. Gray code is a binary numeral system where two consecutive values differ in only one bit. The converter is often used in digital systems where minimizing errors during digital-to-analog conversions is critical.


Examples of weighted and non weighted codes?

Weighted codes assign different significance to each digit in a number representation, such as 8421 BCD code assigns weights of 8, 4, 2, and 1 respectively to each bit. In contrast, non-weighted codes like Gray code do not follow a positional weight pattern, where only one bit changes at a time when moving from one value to another to reduce errors in analog-to-digital conversion systems.


What is the difference between weighted and non weighted codes?

what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc
