the techniques discussed thus far‚ the encoder operates independent of the decoder in order to combat the effects of transmission error in the video bitstream. In a situation where both the encoder and decoder are required to interactively combat transmission losses‚ then a feedback channel can be designed between the decoder and the encoder. The decoder can relay information about which part of the transmitted video data is corrupted by errors‚ and the encoder can strategize its operation to mitigate

is a dialogue not a monologue. So‚ a communication is said to be effective only if it brings the desired response from the receiver. Communication consists of six components or elements. Components of Communication 1. Context 2. Sender/Encoder 3. Message 4. Medium 5. Receiver/Decoder 6. Feedback Context Every message (Oral or written)‚ begins with context. Context is a very broad field that consists different aspects. One aspect is country‚ culture and organization. Every

This requires users to key in numbers in decimals or hexadecimals depending on the encoder that is programmed to the 4X4 keypad. The encoder will provide all the necessary logic inputs for the switches on the keypad. Below are block diagrams of the encoders from Fairchild Semiconductor and there are two different types; DIP(dual-inline

at 1 bit per sample‚ so that audio sampled at 16kHz is encoded at 16kbit/s. The encoder maintains a reference sample and a step size. Each input sample is compared to the reference sample. If the input sample is larger‚ the encoder emits a 1 bit and adds the step size to the reference sample. If the input sample is smaller‚ the encoder emits a 0 bit and subtracts the step size from the reference sample. The encoder also keeps the previous N bits of output (N = 3 or N = 4 are very common) to determine

Abstract In this project an 8x8 multiplier was designed and simulated at the gate level and at the transistor level using the AMS simulator in Cadence Design System. We optimized the multiplier for speed by implementing fundamental building blocks directly in CMOS with the IBM CMRF7SF 0.18um process. Booth’s multiplication algorithm was used to reduce the number of partial products‚ and thus the number of adders‚ providing a speed advantage. Furthermore‚ the adder circuit‚ which is the primary

Convolution codes and viterbi algorithm Name Rahul Kumar Department of Electronics & Communication Engineering Lovely Professional University‚ Kapurthala‚ Punjab. Abstract:- A convolutional code is a type of error-correcting code in which each m-bit information symbol (each m-bit string) to be encoded is transformed into an n-bit symbol‚ where m/n is the code rate (n ≥ m) and the transformation is a function of the last k information symbols‚ where k is the constraint length of the code.

Communication is a two-way process in which there is an exchange and progression of ideas towards a mutually accepted direction or goal. For communication to materialise it is essential that the basic elements of communication be identified and these include the sender‚ the receiver‚ message‚ medium and feedback. Communication is important in our daily lives and so we can’t but communicate. Even when we are not saying a word‚ everything we do is a form of communication. Human communication is predominantly
