Final answer:
The equivalent unit step function for the 'Reetpuls' mentioned would involve subtracting two unit step functions, representing the start and end of the pulse interval, using the format u(t-t0) - u(t-t1).
Step-by-step explanation:
The student appears to be asking about how to represent a rectangular pulse function, often referred to as 'Reetpuls', in terms of unit step functions. In MATLAB, Reetpuls would typically resemble a square wave that's non-zero over an interval and zero elsewhere. When attempting to represent such a rectangular pulse function as a unit step function equation, you would subtract two unit step functions: one that 'steps up' at the beginning of the pulse and another that 'steps down' at the end of the pulse.
An equivalent unit step function for a rectangular pulse starting at time t0 and ending at time t1 would be:
u(t-t0) - u(t-t1)
where u(t) is the unit step function.
