, Select ONE answer for each numbered problem. If you choose more than one on the Scantron sheet, you
will be marked incorrect on that problem.

Data Rate=(Number of Channels)x(samples/second)x(bits/sample)
Capacity=(Number of Channels)x(Bandwidth/Channel)xlog (SNR+1)
2


SNR = Signal Power/Noise Power
AM = Amplitude Modulation
FM = Frequency Modulation
PM = Phase Modulation
FET = Field Effect Transistor
RAM = Random Access Memory

Capacitance=Charge/Voltage
Voltage=Energy/Charge

Light speed=300 million meter/second
(Wave Speed)=(Wavelength)•(Frequency)
(Wave Intensity)=(Source Power) /(4π Distance 2)

kilo=10#
Mega=10$
Giga=10%
1 Byte = 8 bits
1 hour = 3600 seconds
2' =16
2$ =64
2( =256
2)$ =65536
2#* =4294967296
