Detailed Description

VCO similar to NCO but uses floating point.

Voltage controlled oscillator (based on NCO with floating point elements) and complex output. FCW : frequency control word ACC : accumulator Frequency must be set through interface routines set_frequency or reset_frequency. Load routine is to allow frequency to be updated (typically with a loop filter).
