A disciplined oscillator can be modeled by an equation like:
OSC_FREQ = DRIFT_RATE*TIME + TEMPCO*TEMP + OSC_GAIN*DAC_VOLTAGE
For a set of data I know TIME, TEMP, FREQ, DAC_VOLTAGE and OSC_GAIN (a constant in Hz/V).
What the good Lady Heather wants to calculate is the DRIFT_RATE (Hz per sec) and TEMPCO (Hz per degree C).
Does anybody have any code (preferably nice and simple C code) to calculate those two parameters from a data set containing the other 5 values.
