Schematic of a TMDS link used as a link for digital component video data (RGB) between a video controller (PC) and a display controller (Monitor) in interfaces such as DVI or HDMI Transition-minimized differential signaling ( TMDS ) is a technology for transmitting high-speed serial data used by the DVI [ 1 ] and HDMI video interfaces, as well ...
Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator.. Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.
Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.
A conditional loop has the potential to become an infinite loop when nothing in the loop's body can affect the outcome of the loop's conditional statement. However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language , but many share the same basic ...
A receiver can convert a transmitted 1 bit to a 0 bit by pulling the line low within 0.35 ms of the falling edge, and holding it until the 0 bit time. The transmitter observes the bus during its own transmissions to detect this condition. This is used to acknowledge a transmission.
A schematic of a simple superhet broadcast FM receiver. Note that there is no AGC loop, but simply uses a high-gain IF amplifier which is intentionally driven into saturation (or limiting). For single conversion superheterodyne AM receivers designed for medium wave (AM broadcast) the IF is commonly 455 kHz.
The term "receiver" basically refers to an amplifier, typically at least a two-channel stereo model, that has a built-in radio tuner. With A/V receivers, the basic functionality is to receive an audio signal, amplify the audio signal to drive multiple speakers and allow pass-through of the corresponding video signal to a display device such as ...
Previous HDMI versions use three data channels (each operating at up to 6.0 Gbit/s in HDMI 2.0, or up to 3.4 Gbit/s in HDMI 1.4), with an additional channel for the TMDS clock signal, which runs at a fraction of the data channel speed (one tenth the speed, or up to 340 MHz, for signaling rates up to 3.4 Gbit/s; one fortieth the speed, or up to ...
