What occurs when two or more particles are present in the sensing zone at the same time?(a) Calibration(b) Troubleshooting(c) Delay in results(d) Coincidence errorThe question was asked in an online interview.My question comes from Transmission of Video Images topic in section Telemedicine Technology of Biomedical Instrumentation

Answer»

Right answer is (d) COINCIDENCE error

Best explanation: Coincidence error occurs when two or more particles are present in the sensing ZONE at the same time. This will result in the instrument DETECTING fewer particles that are ACTUALLY present. This will also result in the instrument adding the pulses together to produce a single much longer PULSE.
