explain decimal to BCD encoder
An encoder is a digital circuit which accepts one of the inputs and converts it into BCD or Binary Coded Output. It performs the reverse function of that of a decoder.
BCD can be converted into 7segment display by using an encoder.
BCD is a decimal number. BCD is one specific way to store decimal numbers in computer memory.
Explain how an integer can be represented using BCD?
41 in decimal is 0100 0001 in BCD (this is 8 bits not 6 bits)41 in decimal is 101001 in binary (this is 6 bits, but binary not BCD)There is no 6 bit BCD representation of the decimal number 41!
BCD of 862 is 100001100010
BCD (Binary Coded Decimal) output can be generated using decimal-to-BCD conversion algorithms. One common method involves dividing the decimal number by 10 and storing the remainder as the Binary Coded Decimal digit. This process is repeated until all decimal digits are converted into BCD form. Alternatively, some microcontrollers have built-in instructions to directly convert decimal numbers to BCD format.
In Binary-Coded Decimal (BCD), each decimal digit is represented by its own four-bit binary equivalent. Since the highest decimal digit is 9, the highest number in BCD corresponds to the decimal number 9, which is represented in BCD as 1001. Thus, the highest BCD representation for a single digit is 1001. For multiple digits, the highest number would be 999, represented in BCD as 1001 1001 1001.
A 4 BCD code is a 4 decimal-digit BCD code, thus a 16 digit binary-code. You take the decimal number 3545. It's BCD code is 0011 0101 0100 0101 where every 4 bits represent a decimal digit.
The advantage of encoding a decimal number in Binary-Coded Decimal (BCD) compared to straight binary is that BCD allows for easier human readability and manipulation of decimal numbers. Each decimal digit is represented by its own binary sequence, making it straightforward to convert between decimal and BCD without complex calculations. This is particularly useful in applications such as digital displays and calculators, where decimal output is required. Additionally, BCD can simplify certain arithmetic operations involving decimal numbers.
BCD is used for binary output on devices that only display decimal numbers.
