SIP385 Biomedical Instrumentation
The course contains two prewired panels with a variety of cables and accessories. It provides training in basic monitoring circuitry, such as ECG, EEG, EMG, pulse rate, GSR, and temperature monitors. Safety is stressed in the program, and live measurements can be made on students. The course provides for approximately 75-100 hours of instruction.

![]() |
Control Switches for varying rolloff frequencies and amplifier gain |
C Optocoupler isolates the front end amplifier and reference ground from earth ground circuitry
D Signal Processor provides gain for such signals as the R wave in an ECG signal
E 60 Cycle Notch Filter can be switched in or out of the circuit to provide 50/60 Hz trapping
F 8-14 Hz Amplifier is designed to provide bandpass for signals in the 8-14 Hz region
G Output Amplifier provides additional gain for recording various physiological signals
H Isolated Power Supplies to isolate the front end amplifier from the common earth ground
I Polarity Correction Circuitry enables the R wave to be either positive or negative; the output
is always a positive signal
J Pulse Stretching Circuit uses the R wave as the signal and converts it into a rectangular pulse
K Tone Generator produces the tone whose on period is controlled by the Pulse Stretcher Circuit
