Pulse Generator

Block Screenshot


This block is a Pulse Generator. It generates a pulse at a rate of 1/P where P is the period of the signal. The Phase delay gives the value (in time) of the first event. The Phase delay known also as Offset must be less than the Frequency*(1-(Pulse_Width/100)). The second parameter of the block gives the Pulse width and the fourth parameter gives the Pulse amplitude.

Dialog box

  • Phase delay (secs)

    The offset of the block. It must be less than Frequency*(1-(Pulse_width/100)).

    Type 'pol' of size -1.

  • Pulse Width (% of period)

    The pulse width. It can take values from 1 to 100.

    Type 'pol' of size -1.

  • Period (secs)

    The Period of the signal.

    Properties : Type 'pol' of size -1.

  • Amplitude

    The amplitude of the pulse. It can support all scicos types.

    Properties : Type 'mat' of size [-1,-1].
