What are the advantages of FSK?
-> frequency shift keying promotes long distance communication. ->it has high security. ->low noise ->efficiency is high. ->decoding of signal is easy.
What is the relationship between the minimum bandwidth required for an FSK system and the bit rate and the mark and space frequencies?
In Frequency Shift Keying (FSK) systems, the minimum bandwidth required is influenced by the bit rate and the mark and space frequencies. According to Carson's Rule, the bandwidth can be approximated as twice the sum of the frequency separation (the difference between mark and space frequencies) and half the bit rate. Therefore, as the bit rate increases, the required bandwidth also increases, necessitating wider frequency separation between the mark and space frequencies to maintain signal integrity. This relationship ensures that the FSK system can effectively transmit data without interference or distortion.
What is power spectral density of FSK signals?
Power spectral density (PSD) of Frequency Shift Keying (FSK) signals describes how the power of the signal is distributed across different frequency components. In FSK, information is transmitted by varying the frequency of a carrier wave between predefined discrete values. The PSD typically shows peaks at the frequencies corresponding to the modulated symbols, along with side lobes that arise from the modulation process. The overall shape and bandwidth of the PSD depend on the modulation index and the symbol rate, influencing the signal's performance in terms of bandwidth efficiency and susceptibility to interference.
How do you calculate minimum bandwidth that a signal requires PSK?
To calculate the minimum bandwidth required for a Phase Shift Keying (PSK) signal, you can use the formula: ( B = \frac{R}{2} ) for binary PSK (BPSK), where ( B ) is the bandwidth and ( R ) is the data rate in bits per second. For higher-order PSK, such as QPSK or 8-PSK, the bandwidth can be calculated as ( B = \frac{R}{k} ), where ( k ) is the number of bits per symbol. Additionally, considering the required filtering and the Nyquist bandwidth, the actual bandwidth may be slightly wider to accommodate spectral shaping.
Why do you calculate bandwidth?
Bandwidth is calculated to determine the maximum data transfer rate of a network, which is crucial for assessing performance and efficiency. Understanding bandwidth helps in optimizing network resources, ensuring that applications run smoothly, and preventing bottlenecks. It also aids in planning for future network expansions or upgrades by identifying current limitations. Overall, calculating bandwidth is essential for effective network management and delivering a quality user experience.

Why FSk is good choice for low speed modem?
FSK is not always used for high-speed data communications, since it is far less efficient in both power and bandwidth than most other modulation modes. In addition to its simplicity, however, FSK has the advantage that encoded signals will pass through AC-coupled links, including most equipment originally designed to carry music or speech.
Why psk is better then fsk and ask?
Phase Shift Keying (PSK) is often considered superior to Frequency Shift Keying (FSK) in terms of bandwidth efficiency and resilience to noise. PSK encodes data by altering the phase of a carrier signal, allowing for higher data rates within the same bandwidth compared to FSK, which changes the frequency. Additionally, PSK is less susceptible to amplitude variations, making it more reliable in environments with signal degradation. Overall, PSK is preferred in many digital communication systems for its efficiency and robustness.
