Description

Sign component returns a sign value of the input signal.

If the input signal is positive, returns the value 1. If the input signal is negative, returns the value -1. If the input signal is zero, returns the value 0.

The equation described below represents the behavior of the sign component.

Figure 2 illustrates the behavior of the sign component.

Ports

  • Input (in)
    • Input signal to be measured.
      • Supported types: uint, int and real.
      • Vector support: yes.
  • Output (out)
    • Sign of the input signal.
      • Supported types: uint, int and real.
        • The output type is inherited from the input signal.
      • Vector support: yes.
        • The vector length is inherited from the input signal.

Properties

  • Execution rate
    • Type in the desired signal processing execution rate. This value must be compatible with other signal processing components of the same circuit: the value must be a multiple of the fastest execution rate in the circuit. There can be up to four different execution rates, but they must all be multiple of the basic simulation timestep. To specify the execution rate, you can use either decimal (e.g. 0.001) or exponential values (e.g. 1e-3) in seconds. Alternatively, you can type in ‘inherit’ in which case the component will be assigned execution rate based on the execution rate of the components it is receiving input from.
