Scientific calculator was the first company to produce one (Casio fx-7000G). Scientific calculator A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have almost completely replaced slide rules in traditional applications, and are widely used in both education and professional settings. In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the
Integrated Electronics Piezo-Electric the sensor or cable. In between these two limits a functional sensor has been detected. The bias voltage is cut off by a coupling capacitor at the instrument input and only the AC signal is processed further. Piezoelectric sensors which do not possess IEPE electronics, meaning with charge output, remain reserved for applications where lowest frequencies, high operating temperatures, an extremely large dynamic range, very energy saving operation or extremely small design is required. Integrated Electronics Piezo-Electric The abbreviation IEPE stands for Integrated Electronics Piezo-Electric. It characterises a technical standard for piezoelectric sensors which contain built-in impedance conversion electronics. IEPE
