Analog vs Digital
by Seher Sharma
Analog and Digital Technlogy
Digital clocks, cell phones, and computers are all examples of digital signals, because they all use binary code to function. The waves that are being seent out only have 2 amplitudes 1 and 0, making square waves
Analg vs Digital Signals
2.Analog signals are continuous ( meaning they never stop sending), and digital signals are discrete ( they play, then stop, play then stop).
3. The signals for analog, are sent by pulses, and digital signals are sent by electric waves, varrying amplitudes.
Analog (sine wave) vs Digital (square wave)
Vinyl Record vs CD
Analog vs Digital Clocks
Analog vs Digital Technology
2. Analog technology records the waves as is, and does not change them, but digital technology samples the analog waves to a specifically limited set of numbers ans then record them in binary format, 0's amd 1's, to play the data
3. Analog technology cannot keep the quality as good as when it was first played. It degrades each time, meaning that it looses bits and peices of the quality each time it is played, it gets scratched up and plays worse sound(example) quality each time. But on the other hand, digital technology keeps its good quality, it can be played as many times as you want, and it dosent matter, the quality stays the same.
