MPEG audio compression takes advantage of__________ constructing a large multi-dimensional lookup table to transmit masked frequency components using fewer bits.
举一反三
- Audio takes up a lot of space when it is digitized. It is necessary to solve the compression problem of audio signal. Compression has no negative effect on sound quality.

- VLOOKUP函数的格式是( ) A: VLOOKUP(lookup value, table array, range lookup) B: VLOOKUP(lookup value, table array, col index num, range lookup) C: VLOOKUP(range, criteria) D: VLOOKUP(lookup value, table array, row index num, range lookup)
- When constructing a frequency distribution, classes should be selected so that they are of equal width.
- True or False: When constructing a frequency distribution, classes should be selected so that they are of equal width.
