True
Each signal in Time-Division Multiplexing transmits 2 units every 3T seconds.
False
A T-1 carrier carries Digital Signal 2 (DS-2) that combines 24 voice channels into a digital stream.
False
The bit rate for T-1 carrier system is 1.544 Mbps.
True
Telephone subscribers are connected directly to Toll CO in the network structure.
False
Framing is not required for telephone digital transmission.
False
TV stations do not require guard bands.
False
Twisted Pair Cables can achieve significant savings by combining many signals into one.
False
Reliable communications are possible if the transmission rate R is less than the channel capacity C.
True
Frequency-Division Multiplexing involves dividing channels into time slots instead of frequency slots.
False
The formula for Shannon Channel Capacity C is C = Bc log2 (1 + SNR) bps.
True
Multiplexing always involves using multiple cables for data transmission.
False
In Frequency-Division Multiplexing, individual signals occupy frequency slots, not time slots.
True
Bandwidth Bc and Signal-to-Noise Ratio (SNR) are the factors that determine the Shannon Channel Capacity C.
True
Circuit switching involves establishing a dedicated communication channel before data transfer begins.
True
