DL 3155BIO6
Technical specifications
PULSE RATE - didactic equipment - This board must explain the concepts of
the cardiac rhythm and pulsations.
TECHNICAL FEATURES
THEORETICAL TOPIC COVERAGE - Concept of cardiac rhythm and typical
values (in different subjects and in different conditions of the subject),
measurement of the cardiac frequency, the use of optical sensors,
comparator with hysteresis for the processing of the signal provided by the
optical sensor, PLL - frequency dividers - PIC and their role in the
measurement and visualization of the cardiac rhythm. Fault simulation.
CIRCUIT BLOCKS - Recordings of the peripheral pulsations in a finger, effects
of breathing and exercising on the frequency of the pulsations, effects of the
temperature on the measurement of the frequency of the pulsations. It must
be possible to perform the following experiences : frequency response, preamplification of the optical signal, variable amplification stage (circuit
response), amplification of the optical signal, Schmidt trigger (circuit
response), squaring of the optical signal, frequency multiplier (circuit
response), evaluation of the performance, compared analogue and digital
measurement. The faults must be inserted by microswitches; the module
must be provided with a EISA BUS 31+18 INTERFACE, connections and test
points by 2mm terminals. The module must be supplied with a theoretical
and practical manual. Dimensions: 297x260mm.
