Can't find analog signals in Simulink (sf_boiler example)

Hi Everyone! I'm currently writing my postgrad thesis about integration of heterogeneous components and I took the 'sf_boiler' example from Simulink because inside the digital termometer there is an ADC but the real question is: where I can actually understand that a signal is analog? Not from the code because it's always 'sfix'! So if there is an ADC converter there MUST be, defined somewhere or somehow, that the input signal is analog.

Can anyone please tell me how to understand this? I'm stucked on this problem and I can't go on with my thesis!

Thanks to everybody in advance!

Best Regards,

Diego

From what I understand, the ADC basically quantizes the signal, and converts a double value to a fixed-point (limited precision) signal. So the "sfix" signal is the discretized version of the analog (double) signal.

I'm agree with you but this means that it's impossible to understand by looking at the code if a signal is analog or not. I was looking for a clear way to understand if a signal is analog or digital
