Digital control signal

The individual pulse programmer operates at a clock frequency of 160 MHz, and the digital control signals can be generated with the minimum width and increment of 25 and 6.25 ns, respectively.

In practice, a stored reference curve of the cavity pressure or cavity temperature is frequently used to quickly and easily display changes in the process. Modern monitoring systems are now also able to clearly and reliably analyze complex processes such as rotary table applications or multi-component processes with the help of digital control signals in real time. 

The development of digital control computers and of chromatographic composition analyzers has resulted in a large number of control systems that have discontinuous, intermittent components. The nature of operation of both of these devices is such that their input and output signals are discrete.
