Abstract
An apparatus includes a processor, a Phase-Locked Loop Waveform Generator (PLLWG), a Voltage Controlled Oscillator (VCO), a demodulator, signal conditioning circuitry, and an Analog-to-Digital Converter (ADC). The processor generates control command signals, receives a digital data input signal, and performs spectrum analysis on the digital data input signal. The PLLWG is coupled to the processor, receives the control command signals, and generates a charge pump output signal based on the control command signals. The VCO is coupled to the PLLWG, receives a tuning signal based on the charge pump output signal, and outputs a VCO output signal based on the tuning signal. The demodulator receives an incoming modulated signal and the VCO output signal, and outputs an analog output signal based on the incoming modulated signal and the VCO output signal. The ADC converts the analog output signal into the digital data input signal.
