An inverter has a measured delay of 2ns. If five identicalinverters are connected in series, where the the first one isconnected to the last inverter, such that the voltage at the firstinverter will
Design an even parity generator for a 3-bit word. This circuit will have three inputs(the 3 bits of the word) and oneoutput. This output should be 1 if there is an odd number of1s in the input word;
consider a 4-bit counter that couts from 3 (0011) to 12 (1100)and then wraps around. If the counter enters an unused state(such as 0000) because of noise, it will restart from 0011 at thenext rising
