Emulation of communication waveforms
Abstract
An apparatus is comprised of a processor, a tuning voltage generator, a tuning circuit, an amplifier, and a voltage-controlled oscillator (VCO). The processor generates a tuning voltage command and a modulation command signal. The tuning voltage
generator, coupled to the processor, receives the tuning voltage command and generates a baseline analog tuning signal based on the received tuning voltage command. The amplifier, coupled to the tuning voltage generator, receives the baseline analog
tuning signal and the modulation signal, and generates a tuning signal based on the received baseline analog tuning signal and the received modulation command signal. The VCO, coupled to the amplifier, receives the tuning signal, generates a modulated
radio frequency output signal based on the received tuning signal, and outputs the modulated radio frequency output signal, the modulated radio frequency output signal emulating a communication waveform
