Interpolation of a signal in Cadence

[justanengineer]

hello,

i have a square wave signal with variable periode, length of 1 ms.

i want to interpolate the signal at 30kHz. how i can do it?

Thanks

What do you mean with interpolate? Modulate? How? AM? FM? Show a picture!

 

[justanengineer]

i mean Linear interpolation! like sampling my signal at 30khz of frequency

So you want to sample your square wave signal with 30kHz, e.g. to measure the lengths of the low and high phases?

If I understand this correctly, you could use a 30kHz controlled comparator which triggers 2 start-stop-counters.
Or simply 2 start-stop-counters running at 30kHz, triggered by the rising and falling edges of your square wave signal.

Is there anyway to use the cross() and the value() function on the calculator? and how ?

You are (just) an engineer, aren't you? Read the calculator doc!

If you dont know how do do it! Dont comment... other engineer" will do
