Multiple choice

A 6 MHz channel is used by a digital signaling system utilizing 4 level signals. What is the maximum possible transmission rate?

  1. 1.5 Mbaud/sec

  2. 6 Mbaud/sec

  3. 12 Mbaud/sec

  4. 24 Mbaud/sec
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The maximum symbol rate (baud rate) is twice the bandwidth for a baseband channel (Nyquist limit). With 4-level signals, each symbol carries log2(4) = 2 bits. However, the question asks for transmission rate in Mbaud/sec, which is 2 * 6 MHz = 12 Mbaud/sec.

Multiple choice

In Time Division Multiplexing,

  1. several signals are sent on separate channels

  2. several signals are sent in a time slotted mode on a channel

  3. one signal is sent to several users

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by assigning each signal a specific time slot.

Multiple choice

Television signals cannot be received ordinarily beyond a particular distance due to

  1. weak of the signals

  2. weak antenna

  3. absorption of signals in the air

  4. curvature of the earth
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Television signals travel in straight lines and cannot follow Earth's curved surface. Beyond the horizon (the line of sight limited by Earth's curvature), signals cannot be received without repeaters or satellites. This is why TV reception was limited to a specific distance.
