WHAT IS DIFFERENT BETWEEN ANALOGOUS DATA & DIGITAL DATA?
The word you’re looking for is ANALOG, not analogous. Analog: An example is vinyl records. If you look closely at the groove with a magnifying glass you can see the undulations of the groove. They are an analog (image) of the original recorded sound. The stylus (needle) in the playback turntable traces the wiggles of the groove, and the cartridge converts the movements of the stylus into an alternating current (an analog of the original recorded sound), and sent to an audio amplifier. Digital: When an audio CD is recorded, the source audio signal is examined (sampled) thousands of times a second, and the samples are converted into numbers (ones & zeros), which are burned into the disk. Unlike the vinyl record, the numbers are not an analog of the recorded sound. They are produced by an audio-to-digital (AD) converter, using an algorithm. These numbers are a code representing the instantaneous samples (frequency and amplitude) of the original sound. On playback, the numbers are read via
