In science and engineering, root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. [1] It is widely used in IT operations, manufacturing, telecommunications, industrial process control, accident analysis (e.g., in aviation, [2] rail transport, or nuclear plants), medical diagnosis, the healthcare industry (e.g., for epidemiology ...
Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.
Reverse bias: Although the LED is based on a diode junction and is nominally a rectifier, the reverse-breakdown mode for some types can occur at very low voltages and essentially any excess reverse bias can cause immediate degradation, and may lead to vastly accelerated failure. 5 V is a typical maximum reverse bias voltage specification for ...
RCA manufactured equipment, such as oscilloscopes, for repairing radios, RCA Graphic Systems Division (GSD) was an early supplier of electronics designed for the printing and publishing industries. It contracted with German company Rudolf Hell to market adaptations of the Digiset photocomposition system as the Videocomp, and a Laser Color ...
Indian Head pattern with its elements labeled, describing the use of each element in aligning a black and white analog TV receiver. The Indian-head test pattern was created by RCA at their factory in Harrison, New Jersey. Each element of the card was designed to measure a specific technical aspect of television broadcast so that an experienced ...
Curtis Mathes, Inc., is a North American electronics retailer initially based in Garland, Texas, and specializing in the sale of private label brand electronics and repair services. It manufactured its own brand of televisions in Athens, Texas , until July 31, 1982; ten years later, it filed for Chapter 11 bankruptcy and reorganization which ...
All components were connected via the control bus found on the I/O panel on the back of the TV. The control bus was a unique RCA connector which was colored black. All Dimensia branded components had this control jack and they all interconnected by using RCA plugs that could piggy-back, resulting in a daisy chain which simplified wiring.
On color sets the signal would be extracted, decoded back into RGB, and displayed. Although RCA's system had enormous benefits, it had not been successfully developed because it was difficult to produce the display tubes. Black and white TVs used a continuous signal and the tube could be coated with an even deposit of phosphor.
