Use

Domains: Discrete, Continuous. Size: 1-D. Allowed in: Block Diagrams.

Description - CrossingBoth

This is the block implementation of the event function. The output signal is a boolean which goes from false (0) to true (1) when the input signal crosses zero (offset = 0):

 

output = event (input - offset);

 

If desired, you can change the parameter offset to trigger the event on a non-zero input value.

 

The output of the event block for a sinusoidal input (parameter offset = 0).

Interface - CrossingBoth

Description - CrossingDown

This is the block implementation of the eventdown function. The output signal is a boolean which goes from false (0) to true (1) when the input signal crosses zero with a negative slope (offset = 0):

 

output = eventdown (input - offset);

 

If desired, you can change the parameter offset to trigger the event on a non-zero input value.

 

The output of the event block for a sinusoidal input (parameter offset = 0).

Interface - CrossingDown

Description - CrossingUp

This is the block implementation of the eventup function. The output signal is a boolean which goes from false (0) to true (1) when the input signal crosses zero with a positive slope (offset = 0):

 

output = eventup (input - offset);

 

If desired, you can change the parameter offset to trigger the event on a non-zero input value.

 

The output of the event block for a sinusoidal input (parameter offset = 0).
