6.8) FOM? How is channel How in channel de fined defined in in TOM? Aux Frequency Distribution Multipleting in a networking technique in which multiple data signal, are combined for continuoux transmission via a shared Communication medium. FDM VAN a carrier signal at a dixcrete frequency for each data stream and then combinex many modulated signals. Stereo FM tranmision ure carrier signals referred to as subcarriers which differentiater signal, to left and right channels. TV signals are divided up into different frequency channel. Time Division Multiplexing in a Communication Procery that transmity two (81) more streaming digital signals over a Common channel. In TPM incoming signal, are divided into aquel fixed-length time slots and reamembled into original format. During each time slot a TDM frame is created as a sample of the

signal of a frame also channel. given sub-channel. The conxints of a synchronization 6.9) Multiplexing helpe cont effectiveness by allowing multiple partier to share the cont of a link. The closer that you can get the link to gure 100% utilization, the better off you are. Main thing is Carriex multiple signal on a signal Medium, There is a perfect and definite Klay of transmitting the signals through the medium. so, It's became an option for buxinem Computer Network managex. 6.) In anolog multiplexing, the most used techinque is FDM. This technique usen Various frequencies to combine stream, of data for sending them on a Communication medium an a single channel. an FDM threa are levels where level-1 » 12 voice channel, multiplexed togethu.

Level -2 in which multiplexed 5 basic groups are together. Level-3 is master Group in which to Super groupt get multiplexed Lewelry & jumbo group which has 6 - master groups get multipleted. so, by this FDM in uned to multiplex analog signals. À traditional television transmitter, which sends a number of channel, through a single Cable uning FDM.
