Quantum noise detection: A portable and educational system

designing a low‑noise, high‑resolution, and portable four channel acquisition system for recording surface electromyographic signal

in current years, the application of biopotential signals has received a lot of attention in literature. one of these signals is an electromyogram (emg) generated by active muscles. surface emg (semg) signal is recorded over the skin, as the representative of the muscle activity. since its amplitude can be as low as 50 µv, it is sensitive to undesirable noise signals such as power‑line interfer...

Research on Portable Fatigue Signal Detection System

According to the characteristics of human pulse wave signals, the acquisition system acquisition system with excellent performance is designed, 16 bit MCU MSP430 with ultralow power is used to record, process and transmit the collected pulse wave signals. In order to make the hardware part satisfy acquisition requirements of pulse wave, the paper focuses on discussing composition, operating pri...

The Ghetto Bastard: A Portable Noise Instrument

Due to the accelerating development of ‘rapidly to become redundant’ technologies, there is a growing mountain of perfectly serviceable discarded electronic devices hiding quietly at the bottom of almost every domestic rubbish pile or at the back of nearly every second hand shop. If you add in to this scenario the accelerating nature of our society where people don’t have time or the motivation...
