This model implements a first order quantization method, translating the real input into series of messages with value equal to the input signal.
A message is generated every time the input signal changes its value in a quantum q. The Threshold parameter is used to define the accuracy in the detection of the signal variation. The EType parameter defines the value for the type variable of the generated message.
