basically in channel encoding we used to add redundant bit(additional bits) into the transmitting signal so to make it robust against the errors that may be occur during its transmission and receiver these error can be detected and corrected when this signal is passed through channel decoder

What is the purpose of a channel encoder and decoder in modern communication systems?
channel encoder inserts additional information to the transmitted bit stream to facilitate error detection and correction at the receiver. channel decoder is quite opposite to the channel encoder which transmits desired data after the error detection and correction .
What is difference between source encoder and channel encoder?
A source encoder converts client input to a binary stream. This is typically done by sampling an analog input, digitizing the samples and coding them into a binary stream. A common component that does all this is called a Codec. A channel encoder converts a binary stream to an analog signal that can be transmitted over distances as tones, radio waves and/or light. The channel encoder can take a number of bits from the bitstream at a time to create a multibit symbol. The symbols can then be converted to an analog signal for transmission. By transmitting symbols that represent multiple bits, more data can be sent without violating the Nyquist criteria. However, the number of bits that can be coded into a symbol is limited by the SNR as in Shannon's law. A common component that does all this is called a Modem.
How can I use a media encoder to create a video with a transparent background?
To create a video with a transparent background using a media encoder, you can use a video format that supports transparency, such as MOV or WebM, and ensure that the alpha channel is enabled in the encoder settings. This will allow you to overlay the video onto other content without a solid background.
How does shaft encoder work?
A shaft encoder is also known as a rotary encoder. The shaft encoder converts an angular position of a shaft to a digital code.
What is difference between encoder and multiplexer in digital electronics?
An encoder refers to a device that is used to change a signal or data into a code. Whereas a Multiplexer or mux is a device which performs multiplexing or it takes information from more than one channels and outputs into a single channel. Thus a multiplexer is basically a kind of encoder where its function is to combine multiple inputs into one output.
What are the disadvantages of h.264?
Two major disadvantages of H.264 in energy constrained environment are · Encoder complexity · Low resiliency to channel error

Does in Star craft multi player say 'channel is restricted'?
It will say channel is restricted if you have had all chat privileges suspended or you have been banned from that channel.

How does light behave to make rotary encoder work?
A rotary encoder consists of three main parts: light source, optical encoder disc and light sensors. The light source provides the light source to several light sensors. There is an optical encoder disc that selectively blocks light from light source to light sensor. If the light sensor is receiving light, it is first state of electronic circuit. If the light from light source to the sensor is blocked by optical encoder, then sensor is not receiving light and this is second state of sensor output. Therefore, each sensor has two ouputs possible, high or low. Output from one sensor is called a "bit" so for 4 sensors, it is 4 bit output. The light encoder disc is a plastic disc with some area opaque and other areas transparent. Depending upon its rotating position, it passes light to some sensors and blocks light to other remaining sensors. The combination of states of multiple light sensors at a given time due to a certain rotary position of rotary encoder disc is the multi-bit output of that rotary encoder. This multi-bit logic output is used to sense the position, direction of rotation and rotating speed of the rotary encoder. You can read more about rotary encoders at the links given.
