Answer / vidhya

a passive device that implements frequency domain
multiplexing. Two ports (e.g., L and H) are multiplexed
onto a third port (e.g., S).

Answer / vidhya

we can use a signal detection arrangeent which is an
arrangement including a receiver and an enveloped detection
arrangement. The receiver receives radio frequency signals
generated according to a predetermined wireless
communication protocol. The envelope detection arrangement
screens the radio frequency signals for a predetermined
signal which utilizes the predetermined wireless
communication protocol and has a predetermined envelope
sequence. Upon detection of the predetermined signal, the
arrangement transmits a further signal to a computing
device coupled thereto. The further signal is an
instruction for the computing device to execute a
predetermined action. It can be possible through Pulse
Envelope Demodulation method too with unique Digital Signal
Processing algorithms help to prevent false alarms while
differentiating between strong, weak, and interfering
signals.further the combiner is not frequency selective..

Answer / rohit

Answer / nizar

pls mind the question is abt gsm handsets..why it inside in
gsm phone .thats the question...
if my answer is not correct ,hence which device in the
gsm handset will detect reflected and dirct signal or how
gsm phone realize which is the actual...?

Answer / nizar

VIDHYA.SO THIS IS WHY WE ARE USING COMBINER INSIDE THE GSM
HANDSETS.RIGHT..?DETECTING PHASE,RSSI,FREQUENCY,ETC. RIGHT?
....SO THANKS VIDHYA ..

Answer / vidhya

ya you are right friend...

Answer / nizar

this answer is not clear.do you mean if we receive two same
frequency with same content ,will the combiner will detect
the proper one among the two and will [provide actual out?
a frequency deviation may result from obsatcles or
reflected.isnt it right ?

is the syllabus of group1 and group2 same for all graduates like btech,bsc,bcom?
