Question # 3 of 10 PSK is ________ susceptible to noise as compared to ASK. Select the correct optionHighlyMoreEquallyLess

The correct option is "Equally." In terms of susceptibility to noise, both PSK (Phase Shift Keying) and ASK (Amplitude Shift Keying) are equally susceptible. The susceptibility to noise depends on various factors, including the modulation scheme, the signal-to-noise ratio, and the channel characteristics.

Question # 6 of 10 In Phase shift key, _________is/are kept constant. Select the correct optionAmplitude and PhaseAmplitude and FrequencyPhaseFrequency

In Phase Shift Keying (PSK), the amplitude and frequency of the signal are kept constant, while the phase of the signal is varied to represent different symbols or bits. Therefore, the correct option is "Amplitude and Frequency."

Question # 7 of 10 In ASK correct formula for calculating the bandwidth is as ___________. Select the correct optionB=(1+d)SB=(d-1)SB=(d-5)SB=(1*d)S

The correct formula for calculating the bandwidth in Amplitude Shift Keying (ASK) is:

B = (1 + d) * S

Here, B represents the bandwidth, S represents the signaling rate, and d represents the modulation index.

Question # 8 of 10 When certain obstacles block the cellular towers to communicate, _______ are required for long distance communication.Select the correct optionRoutersServersSwitchesRepeaters

When certain obstacles block cellular towers from communicating effectively, "Repeaters" are required for long-distance communication. Repeaters receive the signal from the cellular tower, amplify it, and retransmit it, extending the coverage area and improving signal strength in areas with weak or obstructed signals.

Question # 9 of 10 Which digital multiplexing technique is used to allow several connections to share the high bandwidth of a link?Select the correct optionFDMTDMADMWDM

ChatGPT

The digital multiplexing technique used to allow several connections to share the high bandwidth of a link is "TDM" (Time Division Multiplexing). In TDM, the available time slots of a communication channel are divided and allocated to different connections, allowing them to transmit their data sequentially in a time-division manner.

Question # 10 of 10 Modulation of analog signal is needed if the medium is ___________ in nature. Select the correct optionHigh-passLow-passBandpassBi-pass

Modulation of an analog signal is needed if the medium is "High-pass" in nature. In a high-pass medium, the transmission characteristics of the medium favor the passage of higher frequency signals while attenuating or blocking lower frequency components. Modulating an analog signal allows it to be translated or converted into a higher frequency range suitable for transmission through a high-pass medium.
