Examples described herein include systems and methods which include wireless devices and systems with examples of mixing input data with coefficient data. For example, a computing system with processing units may mix the input data for a transmission in a radio frequency (RF) wireless domain with the coefficient data to generate output data that is representative of the transmission being processed according to the wireless protocol in the RF wireless domain. A computing device may be trained to generate coefficient data based on the operations of a wireless transceiver such that mixing input data using the coefficient data generates an approximation of the output data, as if it were processed by the wireless transceiver. Examples of systems and methods described herein may facilitate the processing of data for 5G wireless communications in a power-efficient and time-efficient manner.

Apparatus and methods remove a voltage offset from an electrical signal, specifically a biomedical signal. A signal is received at a first operational amplifier and is amplified by a gain. An amplitude of the signal is monitored, by a first pair of diode stages coupled to an output of the first operational amplifier, for the voltage offset. The amplitude of the signal is then attenuated by the first pair of diode stages and a plurality of timing banks. The attenuating includes limiting charging, by the first pair of diode stages, of the plurality of timing banks and setting a time constant based on the charging. The attenuating removes the voltage offset persisting at a threshold for a duration of at least the time constant. Saturation of the signal is limited to a saturation recovery time while the saturated signal is gradually pulled into monitoring range over the saturation recovery time.

A system for processing audio signals is disclosed. The system comprises a computer with a digital audio workstation (DAW) software installed, an audio interface coupled to or integrated with the computer, an analog audio processor (AAP) hardware coupled to the audio interface. A digital audio stream from within the DAW software is converted, via the audio interface, to an analog audio signal, then routed through the AAP hardware for fully analog processing and altering, then converted back, via the audio interface, to an altered digital audio stream and finally routed back to the DAW software. The DAW software comprises an AAP plugin which controls a number of audio processing settings of the AAP hardware via a control connection between the AAP plugin and the AAP hardware. The AAP plugin comprises a digital signal processor (DSP) subroutine which applies digital audio effects on the previously altered digital audio stream.
