Also known by its trademarked name of “HD Radio.” integrated circuit intermodulation (or “intermodulation distortion”) input/output International Telecommunications Union (formerly CCIR). ITU-R is the arm of the ITU dedicated to radio. junction field effect transistor inductor / capacitor liquid crystal display light-emitting diode low-frequency low-pass level midrange / high-frequency midrange / low-frequency modulation noise and distortion no connection overshoot IBM-compatible personal computer pulse code modulation peak program meter random-access memory resistor / capacitor Radio (Broadcasting) Data Service—a narrowband digital subcarrier centered at 57 kHz in the TV baseband that usually provides program or network-related data to the consumer in the form of text that is displayed on the radio. Occupied bandwidth is ±2500 Hz. reference radio frequency radio-frequency interference root-mean-square read-only memory subcarrier subsidiary communications authorization a non program-related subcarrier in the TV baseband above 23 kHz (monophonic) or 57 kHz (stereophonic) Sony / Philips digital interface tip-ring-sleeve (2-circuit phone jack) total harmonic distortion transmitter Microseconds. For TV preemphasis, the +3 dB frequency is 1 / (2 ), where is the preemphasis time constant, measured in seconds. voltage-controlled amplifier volume unit (meter) a common style of 3-conductor audio connector crystal
