Abstract:
A light detection and ranging (lidar) receiver may include a first frequency filter to pass a first range of frequencies of an analog signal. The lidar receiver may include a second frequency filter to pass a second range of frequencies of the analog signal that is different from the first range of frequencies of the analog signal. The lidar receiver may include a first analog-to-digital converter (ADC) to derive a first digital signal based on the first range of frequencies of the analog signal using a first sampling rate. The lidar receiver may include a second ADC to derive a second digital signal based on the second range of frequencies of the analog signal using a second sampling rate that is different from the first sampling rate.
