Period is the time to complete ____ cycle

• 1

• 2

• 3

• 4

__________ is the maximum value of voltage or current that occurs in a signal

• Frequency

• Peak Amplitude

• Period

• Vrms

A waveform has 12 cycles in 2 seconds. What is the frequency?

• 1 Hz

• 2 Hz

• 6 Hz

• 12 Hz

Given a frequency of 4Hz, calculate the period.

• 0.25 s

• 1 s

• 1.25 s

• 4 s

In a manchester line encoding, the transition happens at which point of each bit period?

• start

• middle

• end

• no transition

The number of signals units per second that are required to represent those bits is referred to as _________ Rate

The number of bits transmitted during one second is referred to as _________ Rate

An analog signal carries 2 bits in each signal element. If 500 signal elements are sent per second. Calculate the Bit Rate.

• 500 bps

• 1000 bps

• 1500 bps

• 2000 bps

Answer explanation

Bit Rate = Baud Rate * Number of bits per signal element
