Digital caliper. Rather than a rack and pinion, digital calipers use a linear encoder. A liquid-crystal display shows the measurement, which often can switch units between millimeters and fractional or decimal inches. All provide for zeroing the display at any point along the slide, allowing the same sort of differential measurements as with ...
A linear incremental encoder has two digital output signals, A and B, which issue quadrature squarewaves. Depending on its internal mechanism, an encoder may derive A and B directly from sensors which are fundamentally digital in nature, or it may interpolate its internal, analogue sine/cosine signals.
Phase-shift keying (PSK) is a digital modulation scheme that conveys data by changing (modulating) the phase of a reference signal (the carrier wave). The signal is impressed into the magnetic field x,y area by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs , RFID and Bluetooth communication.

More than two years after recalling about 1.7 million Ionic smartwatches sold globally, Google-owned Fitbit will pay a $12.2 million penalty for failing to alert consumers that the products can ...
The standard for a caliper is usually a constant of 0.02 Vernier caliper scale with the normal 0.02 vernier constant, showing measurement of object at 19.44 mm to two decimal places. The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object.
