Answer / pozhilan.s
frequency modulation (FM) conveys information over a carrier
wave by varying its frequency. In analog applications, the
instantaneous frequency of the carrier is directly
proportional to the instantaneous value of the input signa.
Frequency-shift keying (FSK) is a frequency modulation
scheme in which digital information is transmitted through
discrete frequency changes of a carrier wave. The simplest
FSK is binary FSK (BFSK). BFSK literally implies using a
couple of discrete frequencies to transmit binary (0s and
1s) information. With this scheme, the "1" is called the
mark frequency and the "0" is called the space frequency.

Answer / mahendra patil(det)
Both FM and Fsk are
modulation techniques
but simple difference is
fm is analog tech. While
fsk is digital tech.

Answer / mubashir ul zaman
in FM a large range of frequencies is used in correspondence to the input signal but in FSK only 2 frequencies are used corresponding to 1 and 0 of digital encoded signal.

Answer / alberthfmn
remember that fsk is a digital modulation, BUT, it is
transmited as an analog signal.

Answer / sridhar
FM: which means only for analog ..for ex: your voice or
songwhich is automatically modulated with some
frequency ..and then this is carried..like u and bus..after
that bus is removed ..only u reached that place.
fsk..your voice is sampled like 1 or 0.after that if one
means one type of frequency 0 mean one type of
frequncy..which is carried ..
ex" dth...for this more bandwidth required..

yes Mahendra Patil. i am full agree from ur concept... simply we can say FM is a fully Analog while FMSK is Fully DIGITAl

Communication is a process of transferring Data,Voice from one entity to another. Communication processes are sign-mediated interactions between at least two agents, Communication is commonly defined as "the imparting or interchange of thoughts, opinions, or information by speech, writing, or signs
GSM: (Groupe special mobile), previously known as, but now its changed to Global system for mobile comm.. In GSM we use TDMA and FDMA technology both.GSM is developed by European Telecommunications Standards Institute (ETSI).
Basically GSM technology is composed of following things:-
1.SIM (Subscriber identity Module)
2. Cellsites (Genrally we can say Mobile Tower)
3.Electromagnetis waves (Wireless signal or EM Waves)
4.MS (Mobile Station),Mobile handset
