Most post-war European thermionic valve (vacuum tube) manufacturers have used the Mullard–Philips tube designation naming scheme. Special quality variants may have the letter "S" appended, or the device description letters may be swapped with the numerals (e.g. an E82CC is a special quality version of an ECC82)
Mullard initially handled semiconductor naming by using the "O" heater code (shifting "Cold Cathode" to a code of "Z"). The second letter broadly indicated the type of device, roughly following the tube designation, without indicating the semiconductor material: A low-power semiconductor diode, e.g. OA7
Each bit of the RC-5 code word contains 32 carrier pulses, and an equal duration of silence, so the bit time is 64×27.778 μs = 1.778 ms, and the 14 symbols (bits) of a complete RC-5 code word take 24.889 ms to transmit. The code word is repeated every 113.778 ms (4096 ÷ 36 kHz) as long as a key remains pressed.

S/PDIF (Sony/Philips Digital Interface) [1] [2] is a type of digital audio interface used in consumer audio equipment to output audio over relatively short distances. The signal is transmitted over either a coaxial cable using RCA or BNC connectors, or a fibre-optic cable using TOSLINK connectors.
Use of the Philips circle pattern was in its test card broadcasts until 17 February 2001 between 12:00 AM and 06:00 AM (the next day, bTV started 24-hour transmissions), and 2 times a year during transmitter maintenance until 2013. The Philips circle pattern was also used in Hungary, [161] Belgium, [162] [163] Norway, [164] [165] and Sweden. [166]
