Zacurate Fingertip Pulse Oximeter As great as the ICE Contact you just created is, we have a high-powered, fully loaded version in our book “The ICE My Phone Kit” along with step by step directions for ICEing iPhones, Galaxies, regular androids and even phones that are, shall we say,...
Figure 1The “digital electricity” system transmits about 700 energy pulses per second, while monitoring the line for any abnormal conditions that would mandate near-instant shut-off. (Source:VoltServer) The stated benefit is that the energy is so low that the wiring does not need an electric...
Pulse code modulation (PCM) is a digital representation of an analog signal that takes samples of the amplitude of the analog signal at regular intervals. The sampled analog data is changed to, and then represented by, binary data. PCM requires a very accurate clock. The number of samples pe...
1. What is Pulse-width Modulation? Pulse-Width Modulation, or PWM for short, is a scheme that uses digital signals to simulate changes in analog signals, as most of the signals in our natural life are analog, such as brightness, speed, volume, etc. However, analog circuits tend to be ...
What is digital health as we know it today? Digital health plays an increasingly important role in healthcare today. In general, it refers to information and communications tools, devices, software, platforms and sensors used in healthcare to diagnose disease, manage illnesses, identify health risk...
What is pulse Doppler radar?Waves:A wave is a disturbance that propagates from one point to another and possesses certain quantities like frequency, speed and wavelength. Waves are broadly divided into two groups of mechanical waves that require a medium to travel from one point to another, ...
These eight channels provide parallel data streams for the analog I/O, digital I/O, and all four counter/timers. With an expanded 127 sample FIFO for each of the four 32-bit counters, it is now possible to perform buffered counter operations, such as event counting or generating a PWM ...
Pulse frequency modulation is not new, but many engineers are still unaware of it. When we use the term ‘PWM,’ most people immediately recognize this as pulse width modulation, the conversion of a 0% to 100% scale of values into a digital value. Only the duration of a pulse needs ...
