What is included in the system to facilitate playback and study of EMG

1.	What is included in the system to facilitate playback and study of EMG sound waveforms at a later convenient time?(a) Preamplifier(b) Oscilloscope(c) Tape Recorder(d) Ground ElectrodeI had been asked this question in a job interview.This intriguing question originated from Measurement of Respiration Rate topic in division Patient Monitoring System of Biomedical Instrumentation
Answer» CORRECT choice is (c) Tape Recorder To explain I WOULD say: The tape recorder is included in the system to facilitate playback and study of the EMG sound waveforms at a later convenient time. The WAVEFORM can ALSO be photographed from the CRT SCREEN by using a synchronized camera.
