Digital television is simply the process of broadcasting a digital signal, instead of an analog one. This results in better sound and picture quality, as well as increased coverage.
The 555 is not a sound chip, it is a general purpose programmable timer. As such, it is possible to program it to generate sounds or clock digital sound synthesizer chips.
The digital recording gear is much cheaper and lighter than the analog gear. So everybody can feel like a real sound engineer if one has a sound card - but one can still study "Tonmeister". The sound does not depend on the difference between digal and analog. It comes from excellent playing artists in a room with good acoustics, studio microphones, and a sound engineer with sensitive ears.
The big difference is inputs and outputs. Digital ICs expect high/low true/false inputs and outputs. Analog ICs take any inputs, and produce outputs of any level. For example, an audio amplifier is an analog IC. It takes an analog input (sound), and produces an analog output (louder sound). A ripple counter is an example of a digital IC. It takes a digital input (clock pulses), and produces a number of digital outputs (the digital outputs of the flip flops, collectively representing a number in binary).
It quantizes it into discrete points represented by zeros and ones (digital information). The number of samples must be at least two times the highest frequency component of the analog wave. The number of bits in each sample determines how close the digital information is to the actual value of the analog signal.
Synthesizer's create sound from digital instructions.
Digital sound is a rather silly name. Digital refers to how the sound is stored, as a huge number of ones and zeros. Ths stream of ones and zeros can then be fed as instructions to something like a computer, or something that works like a computer, and the computer will understand the instructions and turn them into something called an analouge(or analog)electric signal which then can be turned into sound by a set of headphones or speakers. Sound, the "thing" that we hear, is never digital.
A digital voice recorder works by capturing analog audio through a microphone and storing it in digital files. Some digital voice recorders are voice operated.
what is the difference between digital sound and digitized sound
Original.It changes the sound (pressure waves in the air in the room) into a digital signal.Correction:It changes the sound pressure waves into an ANALOG signal. Any digital signal is the result of feeding the analog mic signal into an analog-to-digital converter, typically in a computer's sound card.Original.An electric guitar doesn't need a microphone because it makes a digital signal.Correction:A simple guitar with magnetic pickups creates an ANALOG signal from the motion of the strings, typically tens to low hundreds of millivolts. If you want a digital signal, you need: 1. Analog-to-digital processing in the guitar itself, or2. Analog-to-digital processing externally, such as a computer sound card.Original.An mp3 recording is a digital signal.
The Bell telephone Company invented digital sound in 1943.

A sound creates vibrations
A sound creates vibrations
Yes, there are digital clocks available that offer different sound options.
AD is Analog to Digital conversion the use is to do digital measurements of analog voltages and currents, a computer soundcard is an AD converter that convert analog sound to digital sound so that it can be played on a computer, and DA is the opposite, digital to analog conversion, the digital sound on the computer is converted to analog sound to drive a speaker or headphone
The vibrations from your lips are what creates sound
