🔍 Key Concepts

• Pulse-code modulation (PCM) works by sampling analog signals and encoding them into digital bits. • In time-division multiplexing (TDM), several signals share the same channel by taking turns in precisely timed slots. • Think about what must stay precisely aligned between the transmitter and receiver so each time slot and each bit is interpreted correctly.

💭 Think About

• When multiple digital signals are interleaved in time, what must the receiver know exactly to separate them correctly? • Which choice deals with timing and bit alignment, rather than frequency spacing or amplitude level issues? • If the timing between sender and receiver slowly drifts, which of these options would cause serious decoding errors?

✅ Before You Answer

• Identify which option refers to timing/clock alignment rather than frequency, amplitude, or power issues. • Ask yourself which factor is absolutely critical for correctly identifying each time slot in TDM. • Eliminate any answers that mainly apply to analog modulation depth or RF frequency separation, not digital PCM/TDM.
