Pertains to electronic components that control or provide an electrical resistance to circuits. Pages in category "Resistive components" The following 33 pages are in this category, out of 33 total.
The resulting free electrons (and their hole partners) conduct electricity, thereby lowering resistance. The resistance range and sensitivity of a photoresistor can substantially differ among dissimilar devices. Moreover, unique photoresistors may react substantially differently to photons within certain wavelength bands.
Off-air capture of a UEIT-2 test card Recreation of the UEIT-2 test card ТИТ-0249, monochrome predecessor of the UEIT test card. UEIT - Universal Electronic Test Chart (russian: УЭИТ - Универсальная электронная испытательная таблица) is a Soviet/Russian test card, designed to test TVs operating in the analogue SECAM colour standard.
Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics which work primarily with analog signals. Despite the name, digital electronics designs includes important analog design considerations.
