ASCII and binary representation, stepped waveform and color representation in graphics
ASCII representation
ASCII representation for B in terms of is as follow:
1. Decimal: 066
2. Octal: 102
3. Hexadecimal: 042
4. Binary: 01000010
Binary representation
Binary representation of 18 is 00010010
Steeped waveform
The stepped waveform diagram of a digital sound is represented as:
On the x-axis represents the time and y- axis represents the signal strength. When wave comes on its axis again, the duration of time is known as one time period.
Representing color in graphics
RGB in graphics is a way of specifying color in graphics and a powerful tool for viewing color. Graphics algorithm manipulate RGB color and the images produced by the graphics algorithm are encoded as RGB pixels and display on the device that render these pixels by emitting RGB light
