It is divided into three parts: analog signal processing unit, wireless data transmission unit, and digital processing unit.
The processing unit converts the analog signal generated by the sensor module into digital format by a built-in analog to digital convertor (ADC) and sends the data frame to the transceiver via a serial peripheral interface (SPI) bus.
The analog pressure readings were sent to a signal processing unit and then to the NI-DAQmx8.9 (National Instruments Corp., Austin, TX, USA) which performed analog to digital conversion.
In Equation 1, P offset accounts for the combined heterogeneity of the RF front-end, analog-to-digital converter (ADC) and the processing unit.
In recent years, system-on-chip (SoC) solutions incorporating a radio transceiver, an analog-to-digital converter (ADC), and a central processing unit (CPU) in a single integrated circuit have become commercially available[17 20].
The forebrain field potential was recorded via a high gain amplifier (upper left), the amplifier output was fed to a central processing unit (CPU) by way of an analog to digital converter (ADC), and the CPU estimated the scalar entropy in real time (Fig. 3B).

In addition, Samsung just announced the Bio-Processor, which embeds a variety of analog-to-digital converters on top of a low-power mobile processing unit.
The considered programmable computational unit (Figure 1) is a low power SIMD machine based on analog processing [13].
