Study Notes
Basic Biomedical Recording System Components
- A basic biomedical recording system has three essential components: electrodes/transducer, signal conditioner, and writing system.
- The electrode/transducer detects and converts the physiological signal into a usable electrical output.
- The signal conditioner prepares the electrical signal from the electrode/transducer to be compatible with the writing system.
- The writing system generates a visual representation of the physiological variable of interest.
