what is the difference between source coding and channel coding?

Source coding is all about studying the structure of the information that is to be stored or sent over a channel and representing the data using minimum number of bits while channel coding involves error detecting and error correcting codes.

For files with more channels (e.g. surround sound), you want correspondingly higher bit rates. So basically, you could hear the difference 160 and 320 kbps if there are more than 2 channels, as bitrate per channel will be lower. Bitrate is affected by bit-depth.

In Python, the source code is compiled into a much simpler form called bytecode. ... py file. The Python implementation compiles the files as needed. This is different than Java, for example, where you have to run the Java compiler to turn Java source code into compiled class files.

There're two types of coding methods, deductive and inductive. Deductive coding is the coding method wherein you have developed a codebook as a reference to guide you through the coding process. The codebook will be developed before your data collection starts, usually in the process of researching the existing field.

Analysis Is More Than Coding “Coding means that we attach labels to segments of data that depict what each segment is about. Through coding, we raise analytic questions about our data from […]. Coding distils data, sorts them, and gives us an analytic handle for making comparisons with other segments of data.”

Simply put, cable channels are those that do not use public airwaves to transmit programs. ... Typically, these channels are paid for by viewers through cable television providers. Broadcast on the other hand usees public airwaves to transmit programs to homes within a limited range.

A medium serves as the means of communication whereas a channel refers to the means of transmission of a message between the sender and the receiver. ... Channel, on the other hand is concrete and could be a letter, a report, a book, a memorandum, a fax, an email, the television, the telephone, etc.

The most obvious difference is that FileStream allows read/write operations, while StreamWriter is write only. The StreamWriter page goes on to add: StreamWriter is designed for character output in a particular encoding, whereas classes derived from Stream are designed for byte input and output.

Source coding are used in order to convert an analog signal to its digitally coded equivalent signal . ... While line coding technique convert the stream of binary digital into format of codes. Example of PCM are RZ, NRZ etc and source coding are Delta and PCM modulation.

MPEG achieves its high compression rate by storing only the changes from one frame to another, instead of each entire frame. The video information is then encoded using a technique called Discrete Cosine Transform (DCT). MPEG uses a type of lossy compression, since some data is removed.

The main difference between machine code and bytecode is that the machine code is a set of instructions in machine language or binary that can be directly executed by the CPU while the bytecode is an intermediate code generated from compiling a source code which can be executed by a virtual machine.

The main difference between source program and object program is that a source program is a collection of instructions written using a programming language, while an object program is an output generated after compiling the source program. A program is a set of instructions that directs the computer to perform a task.

What is the difference between coding and indexing? Coding is the process of reviewing documents and summarizing key elements into a structured database format, like document date and type, Bates number, document description, to whom it is addressed, from whom, etc. Indexing is intended to track electronic documents.

Difference: Unicode is also a character encoding but uses variable bit encoding. Ascii represents 128 characters. Difference: Unicode defines 2^21 characters. Unicode is a superset of ASCII.

The crucial difference between Analog and Digital Communication is that Analog communication uses analog signals for transmission and reception of data while digital communication uses digital signals for transmitting and receiving data.

Machine code is CPU dependent; it is a series of 1s and 0s that translate to instructions that are understood by the CPU. ... Source code is computer programming language instructions that are written in text that must be translated into machine code before execution by the CPU.

Medical coders translate patient care into current procedural terminology (CPT) codes. ... The primary difference, however, is that medical coders translate medical services into codes, while medical billers translate the claims from these codes into reimbursements from insurance and patients.
