True$/$False$.$ Write $"$T$"$ if the statement is true and $"$F$"$ if the statement is false.

The binary code is used to represent various forms of binary.

$203$ The standard ASCII code is a $7-$bit code used in transferring coded information from keyboards and to computer displays and printers.

$q,$

$q,$

A very common output device used to display decimal numbers is the seven$-$segment display.

$q,$

Sequential logic circuits involve timing and memory.

$q,$

The clocked R$-$S flip$-$flop looks almost like an R$-$S flip$-1$lop except that it has one extta

$q,$ input labeled CLK$.$

The J$-$K filp$-$flop has the features of all the other types of flip$-$flops.

$q,$

Flip$-$flops are of fien wired together to form circuits that count.

$q,$

The ripple and asynchronous labels mean that all the fip$-$flops of a counter do not trigger

at one time.

If a decade counter is connected in series with a mod$-6$ counter, the result will be a

$q,$ divide$-$by$-60$ circuit.

In a synchronous counter it is necessary to have all slages of the counter trigger together.

$q,$

The term latch may be used to describe the register used to store data.

$q,$

Shift registers are constructed by wiring flipnflops together.
