Abstract
Systems and methods are provided for generating a hybrid signal. A first signal source is configured to provide a first digital signal having a first sample rate, and a second signal source is configured to provide a second digital signal having a second sample rate. A resampling component is configured to resample the second digital signal into a resampled signal having the first sample rate. A multiplexing component is configured to combine the first digital signal and the resampled signal into a multiplexed signal. A digital-to-analog converter is configured to convert the multiplexed signal into an analog signal.
Claims20
A hybrid modulator system comprising:
- a first signal source configured to provide a first digital signal having a first sample rate;
- a second signal source configured to provide a second digital signal having a second sample rate;
- a resampling component configured to resample the first digital signal into a resampled signal having a third sample rate;
- a multiplexing component configured to combine the first digital signal and the resampled signal into a multiplexed signal;
- and
- a digital-to-analog converter operating at the third sample rate and configured to convert the multiplexed signal into an analog signal.
A method for generating a hybrid signal comprising:
- generating a first digital signal having a first sample rate;
- generating a second digital signal having a second sample rate that is different from the first sample rate;
- resampling the second digital signal to provide a resampled signal having a sample rate equal to the first sample rate;
- multiplexing the first digital signal and the resampled signal to provide a multiplexed signal;
- and
- converting the multiplexed signal to an analog signal.
A method for generating a hybrid signal comprising:
- generating a first digital signal having a first sample rate;
- generating a second digital signal having a second sample rate that is different from the first sample rate;
- resampling the first digital signal to provide a first resampled signal having a third sample rate that is different from each of the first and second sample rates.
- resampling the second digital signal to provide a second resampled signal having the third sample rate;
- multiplexing the first resampled signal and the second resampled signal to provide a multiplexed signal;
- and
- converting the multiplexed signal to an analog signal.
