one type of sensing device - Answer transducer
Sensing Device - Answer A device that picks up information from the experimental set up.
Transducer - Answer A device which transforms data or transduces a non-electrical signal into
an electrical signal that the computer can understand.
(type of sensing device)
-Convert one form of energy to another (mechanical → electrical)
Electrode - Answer A device used to detect electrical events.

One type of transducer - Answer myograph
Myograph - Answer A transducer that measure force of muscle contraction.
Processor (components) - Answer 1. Coupler: modify electrical signal so that it can be
recognized by the remaining components of the recording channel.
2. Amplifier boosts signal proportionall so that we can measure it.
Processor - Answer Device which takes the electrical signal from the transducer.
