/*
 * homodyne.ino: Homodyne detection of a 1 kHz signal.
 *
 * This program continuously samples analog input 0 and uses an homodyne
 * detection scheme to identify a signal at 1 kHz (+/- 24 Hz @ -3dB).
 *
 * The analog-to-digital converter is set to "free running mode" and
 * takes one sample every 104 us. The samples are multiplied by two
 * generated signals at 1 kHz (the "local oscillator"), in quadrature to
 * one another. The products are then low-pass filtered with a time
