Design a 4-bit bidirectional serial-in-serial-out shift register
using S-R flip flops that trigger on the negative–edge transition.
EXPLAIN its operation if binary input 0101 is applied to the
register which initially holds binary data 1101. DRAW the
timing-diagram for serial-in operation in right-shift mode
only.
Design a serial dilution to achieve a final dilution of 10^-4
such that there will be enough solution remaining in each dilution
to use for an assay that requires 100 mL of sample in triplicate.
Remember that better accuracy is obtained with relatively large
dilutions if the total dilution is made from a series of smaller
dilutions rather than one large dilution.
design a 4 bit comparator that compares
two numbers of 4 bits. the output should be < > or =. however
you're only limited to using multiplexers or full adders. any help
on how to draw this will be appreciated
Design a parity bit generator and checker. A system transmits 4
bits of data. Design generator and checker in same schematic use
XOR gate. DO NOT USE KMAPS. Include truth tables. I am trying to
understand the problem. Include boolean expression and explain you
work please. Please explain I need to Learn
Choose two flags (bits) from the 8086 status register, also
known as flags register. In your own words briefly describe the
purpose of each flag and how it works
Design a 1-bt eror correction code for m=8 data bits and r=4
check bits. The 8 data bits are 10101011. For odd parity,assign the
4 check bits ,and give the 22 bits CODE WORD.
1. Design a combinational logic circuit that converts 4 bits
binary to gray code
2. Design a combinational logic circuit that converts gray code to
4 bits binary
3. Design a combinational logic circuit that converts 4bits 2421 to
excess 3 code
