Writing the expression for a realistic Unit Step Function | Ramp Function
A waveform that varies linearly with time, starting at a specific
time t = T, is called a time-shifted ramp function and is
denoted by r(t − T ). If T = 0, it simply is called a ramp
function and is denoted by r(t). In this video, you will learn how to write the expression of a realistic unit step function, but first, we introduce the ramp function and show how to write the expression for the ramp function as well.
