Re: Sweep Generator
Yes, that is the difference. Sawtooth waveforms are used generally, since they are synchronized with a display to show the characteristic.
And it is human nature to like seeing things move from left to right, rather than from right to left, or both ways. (There is no physical reason why you could not do it in reverse, or even both ways, using a triangle wave).
Thus, the display will only be enabled (and refreshed) during the long portion of the sawtooth, while the frequency is being swept from low to high.
