Explain Parity checking error and give an example for each one.

I need an expert solution to the question correctly.

The need to use forward error control is to

30) Coils labeled ( S ) and ( R )A) must appear in that order (S before R) in a ladder logic programB) may be used only in subroutines in programs for Siemens PLCsC) are Short and Repeated coils, used in timing programsD) may be used instead of a seal-in arrangement to provide latching

What is the maximum number of simultaneous faults that a parity bit can detect?

Inpo AND OR Inp1 AND AND Inp2 AND OR Inp3 AND OR Inp4 AND OR Inp5 AND AND Inp6 Assuming that a "NOT" operation is free (zero delay) and that a 2-input gate has a propagation delay of 65 ps and a contamination delay of 25 ps, calculate the propagation delay of the device above. Enter a number (how many ps) in the box below as your answer.

Create a circuit to generate odd parity bit for a 3-bit code. a.  Construct the truth table. b.  Use K-map to simplify the circuit. c.  Draw the circuit with minimum number of gates. (I did the question myself, but I'm confused as to why the K-map does not provide the simplified circuit to build the minimum number of gates)
