Asynchronous pulse generator

image\block_aig_sn.gif

Description of function

The pulse shape at the output can be modified by a configurable pulse/pause ratio.

 

Connection

Description

Input En

You enable/disable the asynchronous pulse generator with the signal at input En.

Input Inv

The Inv input can be used to invert the output signal of the active asynchronous pulse generator.

Parameter

TH,TL: You can customize the pulse width (TH) and the interpulse width (TL).

Retentivity set (on) = the status is retentive in memory.

Output Q

Q is toggled on and off cyclically with the pulse/pause times TH and TL .

Parameters TH and TL

The pulse width TH and the interpulse width TL can be provided by the actual value of another already-programmed function:

You select the required function by the block number.

Description of the function

You can set the pulse/pause ratio at the TH (Time High) and TL (Time Low) parameters.

The INV input can be used to invert the output signal. The input block INV only inverts the output signal if the block is enabled with EN.
