Hello,
EDIT: ------------
Adding maths might help. I'd like to start with some sine:
*sin(2*π*F*t + 
)And then split it into several, delayed, sine waves (here I'll use 2 for clarity):
*sin(2*π*F*t + 
)
*sin(2*π*F*t + 
)Where and are the phase offsets caused by the delay, and A2, A3 are reduced amplitudes according to some distribution (say 
). The phase delays 
and amplitudes 
are then, obv, assessed at the same time. Original Message: -------
I am trying to build a Simulink system where I take a given input singal wave, split it and pass one branch through a delay. The amplitude of the delayed wave would then weighted, and where I can pick any weighting scheme. The output of this combined delay-and-weight would be a signal with some phase offset according to the delay and an amplitude modification from my scheme - e.g. an exponential decay with some time constant. I would then recombine these waves and check the effects of variation in weighting on the interference of the two waves.
I have been able to get a basic sine wave, and to get a manual (static) delay using the Transport Delay block and a static dB loss on that line to approximate this but it owuld be good to build the complete effect.
This might be excruciatingly simple, but I cannot think how to achieve it.
For context, I have a structured light input - sine with frequency F - hitting some fluorescent material, which responds with standard fluorescent lifetime decay physics. The fastest repsonse is effectively instant in my system, but the tail is long. I would like to model what I epxect to see as I, say, increase the frequncy of the input wave or change the decay lifetime of the material. Once I have it working for a simple sine input wave I can then worry about making that input more complicated.
Any help would be much appreciated.
