delay_path()

This function is used to determine the time delay and the constellation rotation angle between two nodal points along a signal path

Syntax
y = delay_path(vin, vout)

Arguments

Name	Description	Range	Type	Required
vin	envelope (I + j * Q) at the input node	(-∞, ∞)	complex	yes
vout	I + j * Q at the output node	(-∞, ∞)	complex	yes

Examples

x = delay_path(vin[1], vout[1])
where vin[1] and vout[1] are complex envelopes around the first carrier frequency in envelope simulation. In return, x[0] is the time delay (in seconds) between vin and vout. x[1] is the rotation angle (in radians) between vin and vout constellations.
or
x = delay_path(T1, T2)
where T1 and T2 are instance names of two TimedSink components.

Notes/Equations

Used in Circuit Envelope simulation, Ptolemy simulation.
This function outputs an array of two values. The first value, data[0], is the time delay between vin and vout. The second value, data[1], is the rotation angle between vin-constellation and vout-constellation.
