How Does a Respiration Rate Monitor Measure Breathing Rate?
TL;DR Introduction A respiration rate monitor measures the number of breaths a person takes per minute. It detects physiological changes associated with breathing, such as chest expansion, airflow, exhaled carbon dioxide, or variations in a pulse oximeter waveform. The device processes these signals, identifies breathing cycles, and calculates respiratory rate. In hospitals, respiratory rate monitoring […]
Understanding Digital Communication Systems: How They Work and Why They Matter
TL;DR A digital communication system consists of electronic blocks that convert information into digital data, transmit it through a communication channel, and reconstruct the original message at the receiver. The information may include speech, text, images, or sensor readings. What makes the system digital is that signal travelling through the channel represents a finite set […]
