TIA Convergent Network Technologies Questions 206–210 (page: 43)

Updated On: 9-Feb-2026

An analog signal's phase measures:

  1. The number of volts from one peak to another.
  2. The time required for the wave to go from peak to peak.
  3. The relative difference between the peak of a signal wave and the peak of a reference wave.
  4. The time required for the wave to move along the channel.

Answer(s): C



A transmitting modem sends a carrier signal to a receiving modem. The purpose of the carrier signal is to:

  1. Carry the transmission over the network.
  2. Establish the bps rate for the transmission.
  3. Carry information about the packets to the receiving modem.
  4. Alter the frequency, amplitude, and/or phase of the transmitted signals.

Answer(s): A



You are sending data over the network and your modem has a maximum speed of 300 bps. What modulation technique is most likely being used?

  1. FSK
  2. KHZ
  3. QAM
  4. DPSK

Answer(s): A



Your modem uses the ITU V.32 modem protocol. This modem modulates the signal by using 1 of 16 different combinations of phase and amplitude. What modulation scheme is being used?

  1. FSK
  2. QAM
  3. KBPS
  4. DPSK

Answer(s): B



In a digital data communication network, the CSU/DSU receives the signal from the
DTE and converts it into what type of signal format?

  1. FSK
  2. QAM
  3. Line code
  4. Equalized

Answer(s): C
