Quickstart ========== .. http://stackoverflow.com/questions/10718767/have-the-same-readme-both-in-markdown-and-restructuredtext * **freqdemod-quickstart-1** [`open html `_]. Here we apply ``freqdemod`` to a sine-wave oscillation, obtaining phase *vs* time data from oscillation amplitude *vs* time data. We fit the phase *vs* time data to a line and obtain a slope that with the known frequency of the sine wave to six decimal places. .. * **freqdemod-quickstart-2** [:download:`open html <../freqdemod/docs/freqdemod-quickstart-2.html>`]. We generate a frequency-modulated sine-wave signal and use ``freqdemod`` to recover the signal's time-dependent frequency. Develop a fast curve fitting algorithm. .. * **freqdemod-quickstart-3** [:download:`open html <../freqdemod/docs/freqdemod-quickstart-3.html>`]. We use ``freqdemod``'s ``fit()`` function to recover transient frequency chenges in two frequency-modulated sine-wave signals (1) a signal that we generate here and (2) a signal generated experimentally by Sarah Nathan in a scanning Kelvin probe force microscope experiment.
