quel type de signal est représenté dans le diagramme ?\nfonction dimpulsion\nfonction rampe\nfonction de pas…

Brief Explanations:

A unit - step function is a function that has a value of 0 for negative time and a non - zero constant value (in this case 1) for positive time. The given diagram shows a function that is 0 for values before a certain point and 1 for values after that point, which is characteristic of a unit - step function. An impulse function is a spike at a single point, a ramp function has a linear increase, and a sinusoidal function has a wave - like pattern.
