Abstract
A system for rejecting a selected harmonic from an input signal is disclosed. The system includes a mixer for creating a signal of new frequency from two input signals of different frequencies. The mixer is coupled to the input signal a frequency generator coupled to the mixer. The frequency generator is configured to generate a signal having a selected duty cycle. The system also includes a controller coupled to a frequency generator.
Claims10
A system for rejecting a selected harmonic from an input signal, the system comprising:
- a mixer for creating a signal of new frequency from two input signals of different frequencies, the mixer is coupled to the input signal;
- a frequency generator coupled to the mixer, wherein the frequency generator is configured to generate a signal having a selected duty cycle;
- a controller coupled to the frequency generator;
- and
- a received signal strength indicator (RSSI) coupled to the controller and the mixer through a switch, wherein the switch is configured to connect and disconnect the RSSI from the mixer.
