In Time Division Multiplexing (TDM), what is the essential receiver component required to recover the signal and identify slot boundaries?
Multiple Choice Options
- A✓ Correct Option
Frame synchronization
- B
Timing pulse generator
- C
Data clock
- D
Sampling signal
Detailed Technical Solution & Explanation
In TDM systems, the demultiplexer must align its time-slot counter with the transmitter's frame structure. Frame synchronization bits (or framing markers) are transmitted at the start of each frame so the receiver can correctly allocate time slots to their respective communication channels.
Option Analysis:
•
Option A (Frame synchronization): Correct. Vital mechanism allowing the receiver to synchronize with multiplexed time slots.
•
Option B: Generates clock pulses, but does not provide frame boundary alignment.
•
Option C: Recovers bit rates, not frame boundaries.
•
Option D: Used during analog-to-digital conversion.
