Spin Semiconductor

Hello! I know that the frequency of ramp LFO's are set by the values -­16384 – 32767. What is the formula to convert a frequency in hertz to this value range?

I found the formula for the sine LFO in the "Basics of the LFOs in the FV-1" pdf, but couldn't find it for the ramp LFO.

Thanks!

We never derived that equation since the circuit was designed for address offsetting rather than as an LFO. You should be able to just write the ramp to a DAC output to measure the frequency for different values and come up with an equation. Note that the equation will be different for different ramp amplitudes.
