In a system for converting digital data into a modulated optical signal, an electrically controllable device having M actuating electrodes provides and optical signal that is modulated in response to binary voltages applied to the actuating electrodes. A digital-to-digital converter provides a mapping of input data words to binary actuation vectors for M bits and supplies the binary actuation vectors as M bits of binary actuation voltages to the M actuating electrodes, where M is larger than the number of bits in each input data word. The digital-to-digital converter maps each digital input data word to a binary actuation vector by selecting a binary actuation vector from a subset of binary actuation vectors available to represent each of the input data words.

Methods, systems, and devices for wireless communications are described. A wireless device, such as a base station and/or a user equipment (UE), may select a first resolution for a first analog-to-digital or digital-to-analog conversion process associated with a first wireless communication. The wireless device may determine that the first wireless communication is performed according to the first resolution. The wireless device may select, based at least in part on the determining, a second resolution for a second analog-to-digital or digital-to-analog conversion process associated with a second wireless communication, the first resolution being a lower resolution than the second resolution.

In a system for converting digital data into a modulated optical signal, an electrically controllable device, including a modulator having one or more actuating electrodes, provides an analog-modulated optical signal that is modulated in response to output data bits of a digital-to-digital mapping. A digital-to-digital conversion provides the mapping of input data words to the output data bits. The mapping enables adjustments to correct for non-linearities and other undesirable characteristics, thereby improving signal quality.

The invention relates to the representation of digital signals. In order to improve the perception by a user of the quality of a digital signal, a first sample of first digital signal is approximated to a second sample of a second digital signal having a second number of significant bits lower than the first number of significant bits of the first sample. The second number of significant bits is also lower than a number of significant bits allowing the second digital signal, or a signal derived therefrom to match an expected bit depth of a processing unit said second digital signal, or a signal derived therefrom is to be sent to.

The invention relates to improved convolutions of digital signals. When a first digital signal is convoluted with a second digital signal to obtain an output digital signal, to be converted afterwards using a limited number of bits. In order to prevent a loss of information, and therefore a degradation of the output digital signal upon the future conversion, at least one of the first and the second digital signal is formed of suitable values that store the information from the first digital signal within the most significant bits of the output digital signal.
