What is MU-law and a-law?
The μ-law algorithm (sometimes written mu-law, often approximated as u-law) is a companding algorithm, primarily used in 8-bit PCM digital telecommunication systems in North America and Japan. ... A-law is used in regions where digital telecommunication signals are carried on E-1 circuits, e.g. Europe.
What is the standard value of mu?
8. What is the standard value of μ in μ-law ? Explanation: The standard value of μ in μ-law is 255.
What is μ law Compander and a-law Compander?
a-law compander is used in european telephone networks. u-law compander is used in telephone systems of USA,Japan. u-law compander has different compression and expansion curves than a-law compander. As both are incompatible,conversion circuits are needed to make both interoperate with each other.
What is μ law quantization?
μ-Law companding is a compression process. It explores the principle that the higher amplitudes of analog signals are compressed before ADC while expanded after digital-to-analog conversion (DAC). As studied in the linear quantizer, the quantization error is uniformly distributed.
