A method for minimizing unwanted signal harmonics from at least one signal in a channel received through a monobit receiver, comprising: conditioning () the channel, determining () relative strength between two frequency components of a signal within the channel, and using that relative strength () to control () how the channel is conditioned. In other embodiments, a system for receiving signals in a channel and minimizing unwanted harmonics from those signals has a monobit receiver (), a channel conditioner (), and a feedback driver () determining relative strength () between two frequency components of a received signal and using that determination to control the channel conditioner in a way that urges the relative strength toward a desired value.

Monobit receiver spurious harmonics control method and system

A system for converting a digital signal to an analog signal, the digital signal having a center frequency, includes: a multi-Nyquist DAC; a clock; and a controller configured to: control the clock to generate a clock signal such that the center frequency of the digital signal is an integer multiple of half the frequency of the clock signal, the clock being configured to supply the clock signal to the multi-Nyquist DAC and to the controller; and supply the digital signal to the multi-Nyquist DAC to generate an output signal.
