there are four paths with delay 3, 6, 9, 21 (in micro-seconds)
for the first path require 3
first to second path require 3
second to third require 3
third to forth require 21-9=12
therefore 3+3+3+12 in total is it?
maximum allowed transmission rate from the sender to the receiver is 21?
Homework Statement
Consider the multi-path propagation phenomenon discussed in class. Assume the signal from a sender takes 4 paths to arrive at the receiver, and the delay along each path is 3, 6, 9, 21 (in micro-seconds), respectively. Each symbol is 1 bit long. Two symbols can be...
I try this
g(t)= sin(2πfct)+ cos(2πfst+π3) sin(2πfct)
g(t)= sin(2πfct)+ (cos(2πfst)+cos(π3)) sin(2πfct)
g(t)= sin(2πfct)+ (cos(2πfst)sin(2πfct)+cos(π3)sin(2πfct))
but don't know how to continue
Homework Statement
Let the baseband signal be
s(t)=cos(2πfst+π3), where fs=5kHz. Radio carrier is
c(t)=sin(2πfct), where fc=100MHz. Using the amplitude modulation of g(t)=(1+s(t))c(t), what is the frequency spectrum of the modulated signal g(t)?
What are the amplitude and phase shift of...
