clock pulse

Fresh data may be supplied and a further clock pulse given.

If the next clock pulse comes before that, the results will be incorrect.

Sometimes a clock pulse is left out to signify a special bit.

The clock pulses have no effect if the data applied to D has not changed.

The main problem with using this circuit is providing the clock pulses.

In real systems, a monostable is used to provide the clock pulses.

This, in turn, provides the clock pulse for the bistable.

The state of a synchronous circuit changes only on the clock pulse.

Apply clock pulses and check that the data shifts along as it should.

A memory chip that transmits data once per clock pulse.

If we subsequently put a 0 on the D input then apply a clock pulse.

A clock pulse is given by pressing switch, S2.

It can be seen that digits move (shift) 1 place to the right with each clock pulse.

If the instruction is direct, nothing is done at this clock pulse.

Now keeping the data switch or switches pressed, apply a clock pulse.

This is how it will remain until fresh data is applied and a further clock pulse given.

Check that clock pulses have an effect only when the data applied to the D-input is new.

This long delay is obtained by deleting two clock pulses.

Transferring several bits on each clock pulse improves the card speed.

So bits that go in come out the other end the number of clock pulses later that this thing is long.

Depending on the type, this may happen on the positive or negative going edge of the clock pulse.

Although in theory any clock pulse may be stretched, generally it is the intervals before or after the acknowledgment bit which are used.

When data is fed into input, D1 and a clock pulse given, the data moves along one place.

On the arrival of a clock pulse, this will be transferred to Q1 so X1 lights.

Upon receiving a clock pulse, every one and zero moves one cell to the right.
