The CANNode PCB gathers analogue sensor data to an 12-bit ADC chip, which then communicates via SPI to an STM32F446RET6 chip. The data is lightly processed and packaged into a CAN2.0-A packet and sent ...

In an FFT representation of converter data, the average noise floor (D) is a root-mean-square combination of all the bins within the FFT plot but excludes the input signal and signal harmonics. You ...

Some models of Delta-Sigma ADC modulators in Python + Matplotlib. Implemented: 1st-Order; 2nd-Order; MASH-1-1; MASH-2-1; Hitting the reset button will reload the modulators.py module, so a small bit ...

Figure 1 An FFT uses sampled data from an ADC. In this FFT plot, there are4096 samples that the converter acquires at a data rate of 200k samples/sec. The SNR(Point C) in this plot is a calculated ...

Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...

Figure 3 The fundamental level is the same as what is represented in the FFT plot, as you can see in this closeup. Coherent calculations. Now it’s time to do a bit of math. The ADC12DJ5200RF, which we ...

This FFT plot shows the test results of a SAR-ADC using coherent sampling with a data record (M) of 32,768 samples. The sampling frequency is locked to fS = 705.882 kHz, and the desired test input ...
