Radio signal from a radio station is transmitted by a wave of
Student No (Last Digit)
0 & 9
1 & 8
Wave Equation
s(t) = 20 cos (67 × 10ºt + 9 sin (2n × 10³t))
s(t) = 30 cos (10 × 10°t + sin (2n × 10°t))
s(t) = 15 cos (47 × 10³t + 6 sin (27 × 10't))
s(t) = 40 cos (67 × 10°t + sin (2n × 10°t))
%3D
2 & 7
3 & 6
4 &5
s(t) = 45 cos (8n × 101²t + 3 sin (2n × 10°t))
Assume R= 10. Calculate the frequency deviation, bandwidth, and power of the FM wave. And
conclude either it is a FM or AM transmission with wide or narrowband.
