Jaguar Input Question

[ErikRantapaa]

Thanks for all of the replies.

It seems that the term PWM can mean different things depending on the context.

In the case of the Jaguar OUTPUT what matters is the duty-cycle, i.e. the percentage of time that the signal is on with respect to its period.

In the case of the Jaguar INPUT what matters is the length of time (i.e. in seconds) that the signal is on.

Yep. This is why I teach it to my students as Pulse Width Modulation and Duty Cycle Modulation. PWM is an over-used phrasing, especially when you really consider what aspect of the pulses matter to you.

For the input, the positive width is critically important, and the total period just needs to be close enough.

For the output, you care about the ratio of on to off, and the frequency.
