What are the advantages and disadvantages of FSK?

Advantages and disadvantages of FSK

• It has a lower probability.
• Easy to implement.
• High data rate.
• It has better noise immunity than ASK method, so the probability of error-free reception of data is high.
• Easy to decode.
• Operate in virtually any wires available.

What are the advantages of FSK and PSK over ASK?

Benefits or advantages of PSK ➨It carries data over RF signal more efficiently compare to other modulation types. Hence it is more power efficient modulation technique compare to ASK and FSK. ➨It is less susceptible to errors compare to ASK modulation and occupies same bandwidth as ASK.

What are the advantages and disadvantages of QPSK?

Advantages and disadvantages of QPSK

• QPSK provide very good noise immunity.
• It provides low error probability.
• Bandwidth is twice efficient is compared to BPSK modulation.
• For the same BER, the bandwidth required by QPSK is reduced to half as compared to BPSK.

What are the advantages and disadvantages of BPSK?

➨BPSK demodulator requires to make only two decisions in order to recover original binary information. Hence BPSK receiver is very simple compare to other modulation types. ➨BPSK is power efficient modulation technique as less power is needed to transmit the carrier with less number of bits.

What is the disadvantage of FSK compared with ASK & PSK?

Following are the disadvantages of FSK: ➨It uses larger bandwidth compare to other modulation techniques such as ASK and PSK. Hence it is not bandwidth efficient. ➨The BER (Bit Error Rate) performance in AWGN channel is worse compare to PSK modulation.

What are the main disadvantage of ASK and FSK?

➨It offers lower power efficiency. ➨ASK modulation is very susceptible to noise interference. This is due to the fact that noise affects the amplitude. Also refer advantages and disadvantages of FSK Modulation >> and PSK Modulation >>.

What are the advantages and disadvantages of ASK modulation?

Advantages and disadvantages of ASK

• It offers high bandwidth efficiency.
• It has a simple receiver design.
• Its generation and detection are easy thus facilitate a simple transmitter and receiver section.
• ASK modulation and demodulation are relatively low-cost methods.

What is advantage of QPSK over BPSK Mcq?

Explanation: The bit error probability of QPSK is identical to BPSK but twice as much data can be sent in the same bandwidth. Thus, when compared to BPSK, QPSK provides twice the spectral efficiency with exactly the same efficiency. 12.

What is the major advantage of QPSK over PSK?

Very good noise immunity. For the same bit error rate, the bandwidth required by QPSK is reduced to half as compared to BPSK. Because of reduced bandwidth, the information transmission rate of QPSK is higher.

What are the main disadvantages of DPSK over BPSK?

Drawbacks or disadvantages of DPSK modulation ➨Probability of error or BER (Bit Error Rate) is higher in DPSK compare to BPSK. ➨Noise interference in DPSK is more. ➨DPSK modulation uses two successive bits for its reception. Hence error in first bit creates error in second bit and consecutively error propagates.

What is the advantage of QAM over ASK and PSK?

PSK modulators are often designed using the QAM principle, but are not considered as QAM since the amplitude of the modulated carrier signal is constant. QAM is used extensively as a modulation scheme for digital telecommunication systems. Noise immunity of QAM is very high. QAM is best suitable for high bit rates.

Which is better FSK or PSK?

PSK modulation techniques are in general better than FSK modulations in terms of bandwidth requirements or in other words PSK modulation schemes offer better bits/s/hz efficiency. However FSK modulation schemes are more power efficient i,e, offers better BER performance at a given S/N (signal-to-noise ratio).
