TDMA:
Time division multiple access (TDMA) is a channel access method for shared medium (generally radio) networks. It permits several users to share the similar frequency channel by dividing the signal into different time slots. The users transfer in rapid succession, one after the other, each using his own time slot. This permits multiple stations to
Share the similar transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity. TDMA is used in the digital 2G cellular systems like Global System for Mobile Communications (GSM), IS-136, Personal Digital Cellular (PDC) and iDEN, and in the Digital Enhanced Cordless Telecommunications (DECT)
Standard for portable phones. It is also used extensively in satellite systems, and combat-net radio systems.
FDMA:
Frequency Division Multiple Access or FDMA is a channel access method used in multiple-access protocols as a channelization protocol. FDMA gives users an individual allocation of one or various frequency bands, permitting them to utilize the allocated radio spectrum without interfering with each other. Multiple Access systems coordinate access among multiple users. The users may also share access by different methods such TDMA, CDMA, or SDMA. These protocols are utilized differently, at dissimilar levels of the theoretical OSI model.
The inputs to an SRFF are shown in Figure. Determine the value of Q at times t 1 , t 2 , and t 3 .
Discuss all the five software interrupt instructions. The INTEL family microprocessor consist of software interrupts INT, INT0, INT3 and BOUND and IRET. Out of all these five
Consider the RL circuit of Figure with R = 2, L = 5H, and v(t) = V = 20 V (a dc voltage source). Find the expressions for the inductor current i L (t) and the inductor voltage v L
Q. The coil is placed so that its axis of revolution is perpendicular to a uniform field, as shown in Figure If the flux per pole is 0.02 Wb, and the coil, consisting of 2 turns, i
Port Address The port address is of 8 bit it is range from 00H to FFH. It means there may be total i 256 input ports and 256 output port which can be accessed by 8085
Q. Give a general account of common drain amplifier? The output is taken over the source terminal and when the dc supply is replaced by its short circuit equivalent, the drain
Explain the term half duplex transmission. A half duplex channel can receive and send, but not at similar time. It's as a one-lane bridge where two-way traffic should give way
