sample and hold flip flop

I need time diagram for an D flip flop and its table of states (control).
Does people use it as S/H circuit (sample and hold) in power electronics control? I mean is it the same in schematics?
 

s/h circuit

Well, u can check this page, it has a nice explanation and the difference between a latch and a flip flop:

**broken link removed**

Also, to use it as sample and hold, i kind of doubt it, remember flip flops are difital circuitery, has two levels at least this kind, high or low, it wouldn't be good for a sample and hold where u need the exact magnitude at a specific time.

You can check out the datasheet of the 74ls74 D type flip flop
 

d flip flop circuit

How to model it in Simulink or Pspice?
 

h circuit

In simulink there are S/H blocks, if that is what u are trying to simulate
 

sample hold flip flop

'Zero Order Hold Block in simulink is a simple version of S/H.
