Advantages, disadvantages and applications of CDMA (code division multiple access)
There are some important advantages of CDMA (code division multiple access) are given below, The CDMA does not require any synchronization. It has more number of users can share the same bandwidth. It is well-matched with other
Difference between PCM and DPCM
Following are the difference between PCM (pulse code modulation.) and DPCM (differential pulse code modulation) PCM DPCM The PCM stands for pulse code modulation. The DPCM stands for differential pulse code modulation. The PCM (pulse code modulation) can
Working principle and construction of PMMC
The PMMC stands for permanent magnet moving coil and it is also called as D’Arsonval instruments. The PMMC works on the electromagnetic effect. A permanent magnet is used to produce magnetic flux and a coil that carries
Advantages and disadvantages of PMMC (permanent magnet moving coil)
There are some advantages of PMMC (permanent magnet moving coil) are given below, The PMMC has uniformly divided scale. The scale may be very long, over about 250 degree. It has a very high torque to weight
Difference between pulse modulation and continuous wave modulation
Pulse modulation Continuous wave modulation The modulated signal is in the form of pulses. The modulated signal is in the form of continuous signals. It is used sampling technique. It is not used sampling technique. It has
Difference between FDMA and TDMA
Following are the difference between FDMA (frequency division multiple access) and TDMA (time division multiple access) : FDMA TDMA FDMA stand for frequency division multiple access. TDMA stand for time division multiple access. The FDMA (frequency division multiple access)
What is IEEE 802.11?
IEEE 802.11 is a combination of media access control (MAC) and physical layer specification used to implement wireless local area network (WLAN) computer communication in the 2.4, 3.6, 5 and 60 GHz frequency bands. The 802.11 family
