Design of a Digital Breathing Rate Tester Circuit

Abstract:

Digital breathing rate tester uses amplifier circuit, filter circuit, shaping circuit, and frequency quadruplicator circuit to process respiration signals. The signals processed are mixed with signals from logic controller circuit, pass the NAND gate, combine with signals from NAND gate and enter the pulse counter circuit. Pulse counter circuit’s digital tube shows the breathing rates.
