What is near audio communication?
Audio communication is easier to create. Faster than typing for most human communication needs is talking. That is why we recommend writers brainstorm their first drafts talking them out into a voice recorder such as tinyvox. Audio communication can also be reviewed by anyone online through new services. The Internet has made audio communication easy again. Nondisposable audio communications such as making a tape are valuable because they allow the author to create content without…
Multimedia Communication : Multimedia : Multi = Many , Media = Medium It means You have Many Medium to Express Your Self.... you can Express by Text and Graphics (images), you can Express by Text ,Graphics ,and Audio you can Express by Text , Graphics ,Audio ,and Video you can Express by Text , Graphics ,Audio , Video , and Animation.
Why the received signal in analog communication is distorted by the channel noise than that of digital communication?
If an RF signal is AM modulated with a analogue signal any noise will add or subtract to the amplitude of the RF signal and will be present in the audio signal after detection, also will the noise add itself to the audio signal, where as in digital communication a slight variation in the amplitude of the signal is of no concern because you only work with ones and zeros, it's high or it's low
The modern form of communication and result of devepment in communication tools is satellite communication which is creating a buzz all where.It is a direct to home way of broadcasting where the signals are caught by an antenna and decoded by a digital decoder and transmitted out via an output medium like TV in the form of tv channels.The quality of audio-video is subsequently better than cable tv.(digital form) While terrestrial communication is a primitive…
In satellite communication uplink (transmission of signal from earth station to satellite ) & downlink (reception of signal from satellite to earth station) takes place TX & RX involves a finite amount of delay which is acceptable in data communication, but i audio & video TX this delay is unacceptable, overlapping/ alaising causes errors which demodulated by qpsk.
Synchronous just means "at the same time," so the difference is basically between immediate forms of communication. Here are some examples: Asynchronous communication: Email Message Boards Letters Blogs Video or Music recordings Online discussion boards Synchronous communication: Phone calls Audio and Video conferences In person concerts Instant messaging / chat In-person conversations / meetings Clearly the synchronous method is much faster, but the method that is best for a specific communication depends on the circumstances.
mp3 was formerly known as MPEG-1 Audio Layer 3. MPEG is a digital encoding format used for transmitting audio sounds and pictures. MPEG stands for Moving Picture Experts Group, the body which established standards for video and audio formats for use by computer-based media communication systems. The MPEG-1 format standard was some two years in development, during the years1990-92. There is also MPEG-2 etc. Whereas MPEG-1 Audio Layer 3 is used for PCs, portable music…
