The count sequence of a BCD down counter is as follows: 1001,1000,0111,0110,0101,0100,0011,0010,0001,0000,1001. . . . . . .
You do it by studying, and doing your homework by yourself instead of trying to get someone else to do it for you.
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
BCD can be converted into 7segment display by using an encoder.
BCD refers to Binary Code Decimal there are no diagrams it is just a numbers system GRAY code is a means to make one reliable state to change at a time eliminating false coding because of transitions in counters and such
detects the invalid portion of the bcd number codes (1010-1111)

BCD code isn't valid for these integers , 10 , 11 , 12 , 13 , 14 i.e if these integers ae converted to binary code they 'd be called wrong BCD
usually just clock & reset.
I wants to know the advantages of 4 Bit BCD/Binary UP/DOWN

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.
it is a cmos decade counter with bcd to seven segment output integrated within the IC
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.
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.
