We present a photon counting experiment designed for an undergraduate physics laboratory. The statistics of the number of photons of a pseudo-thermal light source is studied in two limiting cases: much longer and much ...

This work documents the process of designing, sizing, simulating and implementing a low-cost circuit to emulate an oscilloscope probe, enabling measurements of electrical current with no need for intervention in the circuit ...

New alternatives for monitoring the ceramic grinding process have been studied. Monitoring vibration signals is one of the most successful methods because some characteristics that describe the behaviour and influence of ...

This work deals with the development of a digital oscilloscope with the Raspberry Pi. For the development of applications, concepts about the analog to digital converter will be presented, as well as information about the ...

In this paper we present an algorithm of signal processing that allows the use of a PC-based oscilloscope in order to count events with a time stamping register. This novel application has a direct use on recording of ...

In this work a didactic strategy was designed to teach the physical magnitudes of the waves using vocal technique exercises and two Sound Analysis Oscilloscope and Sound Analyzer App cell applications, which measure the ...

Methylmercury (MeHg) is present in the environment because of natural and anthropogenic causes. MeHg can reach the central nervous system (CNS) and cause neurological damage in humans and animals. Electric organ discharges ...
