Input Ports

This function has no inputs.

Output Ports

Name	Width	Description
Out	<PortWidth>	The output signal
OutDot	<PortWidth>	The derivative of the output signal

Configuration parameters

Name	Width	Description
PortWidth	1	The number of elements in the signal.
Amplitude	<PortWidth>	The amplitude of each pulse.
Period	<PortWidth>	The pulse period (time between pulse centers).
Width	<PortWidth>	The width of the nonzero portion of the pulse [sec]
RiseTime	<PortWidth>	The time from pulse start to final value, and from final value to 0. Must smaller than Width/2
Delay	<PortWidth>	The delay of the pulse train, relative to the first pulse center (starts at T=T_start).
Bias	<PortWidth>	The bias of the pulse signal.
