NettetIf you're talking about a ramp (y=0, t<0; y=t, t>=0), as opposed to some sort of sawtooth periodic wave, think of the ramp as the integral of a step function. The Fourier Xform of the step function is (1/jw). The Xform of … NettetRamp generators are used to produce a sawtooth waveform. Ideally, the sawtooth waveform consists of a voltage which increases linearly with time until it reaches a predetermined final value, instantaneously returns to zero, and immediately increases again as the cycle repeats. One application of this waveform is to produce a linear time …
