In your own words, please explain the relationship between sub-band coding in acoustics and MP3 compression.

The symbol £ is magnified and shown in Figure 1 with a grid superimposed. Figure 1 The image in Figure 1 is to be encoded and encrypted using the following steps: 1. Each of the five horizontal rows of the picture is encoded as a 5-bit binary number. White squares are encoded as Os and black squares as 1s. The horizontal rows are therefore encoded as: Row 1: 00110 Row 2: 01001 Row 3: 11100 Row 4: 01000 Row 5: 11110 2. Starting from the left, the first binary digit is multiplied by 16, the second by 8, the third by 4, the fourth by 2, and the fifth by 1. This will convert the 5-bit binary numbers to decimal numbers as shown below: Row 1: (0 x 16) + (0 × 8) + (1 × 4) + (1 × 2) + (0 × 1) = 0 + 0 +4+2+0 = 6. Row 2: (0 x 16) + (1 × 8) + (0 × 4) + (0 × 2) + (1 × 1) = 0 + 8 +0+0+1 = 9. Row 3: (1 x 16) + (1 × 8) + (1 × 4) + (0 × 2) + (0 × 1) = 16+8+4 + 0 + 0 = 28. Row 4: (0 x 16) + (1 × 8) + (0 × 4) + (0 × 2) + (0 × 1) = 0 + 8 +0+0+0= 8. Row 5: (1 x 16) + (1 × 8) + (1 × 4) + (1 × 2) + (0 × 1)…

For an 8-bit compressed code of 10111101, what is the 12-bit recovered code?

To what extent does the efficacy of encoding techniques differ? What is the current dependency and its rationale?
