Signal acquisition analyzer based on MSP432
نویسندگان
چکیده
Abstract The system is based on digital signal processing technology, takes MSP432P401R single-chip microcomputer as the main controller, uses on-board ADC to convert input into a signal, and then carries out FFT transformation obtain amplitude of each harmonic component, so carry spectrum analysis calculate THD/ THD o / Δ values for further processing. realizes calculation distortion measurement error expands functions calculating normalized fundamental wave recovering waveform. Distortion value ≤3%, can process range 30mV~600mV, frequency 1kHz~100kHz, time less than 10 seconds.

FPGA-Based Signal Acquisition System
This paper presents a high-performance four-channel signal acquisition system composed of frequency channelizers and signal detectors in a single 6U VME slot. The intense computational complexity necessary to implement such an application requires field programmable gate arrays (FPGAs) to achieve a 10x performance density increase over a traditional GPP implementation. The same application perf...
متن کاملSound Signal Analyzer
Analyzer system intended to visualize the sound signal in the time and frequency domain is presented. The system was realized in Matlab and it can process sound signals of wav files. Spectral analyzer takes into account the perception of the sound by humans and thus the magnitude spectrum can be visualized with frequency axis in Barks end ERBs. Spectrum can be weighted by the transfer function ...
متن کاملFast GNSS satellite signal acquisition method based on multiple resamplings
A fast Global Navigation Satellite System (GNSS) satellite signal acquisition method based on resampling is presented. In contrast to traditional approaches, which perform a single-round search with a high data rate, the proposed method introduces a signal acquisition mechanism that uses data resampling. Starting from a resampled data rate slightly above the Nyquist frequency, the proposed meth...
