Q. The frequency from $3 \times 10^{9} Hz$ to $3 \times 10^{10} Hz$ is
Communication Systems
A
High frequency
B
Super high frequency band
C
Ultra high frequency band
D
Very high frequency band
Solution:
$3 \times 10^{9} \,Hz \equiv 3000 MHz =3\, GHz$
$3 \times 10^{10} Hz =30000\, MHz =30\, GHz$
$3\, GHz$ to $30\, GHz$ is higher than UHF $(500-1000 \,MHz )$
represents super high frequency band.
