Given the constraints of the passband channel, the most appropriate modulation scheme to use would be Quadrature Amplitude Modulation (QAM). This modulation scheme is capable of achieving high data throughput, which is necessary for the targeted bandwidth efficiency of 4 bits/sec/Hz.
The symbol rate (SR) should be chosen so that it is within the given passband channel, while also allowing for a high enough bit rate to reach the targeted efficiency. To do this, the SR should be chosen to be in the range of 1Khz to 3Khz, depending on the specific requirements of the system.
The bit rate (BR) should be chosen based on the symbol rate and the targeted bandwidth efficiency. For a given symbol rate, the bit rate can be calculated by multiplying the symbol rate by the number of bits per symbol. For example, if the symbol rate is 1Khz, then the bit rate can be calculated as 1Khz x 4 bits/symbol = 4Kbps.
The raised-cosine roll-off factor should be chosen based on the specific requirements of the system. Generally, a roll-off factor of 0.25 is a good choice and will provide good performance.
The carrier frequency should be chosen based on the specific requirements of the system. Generally, a carrier frequency in the range of 1Khz to 3Khz is a good choice.

What is the significance of modulating index?
The modulation index is a crucial parameter in communication systems that determines the extent of modulation applied to a carrier signal. It affects the bandwidth and power efficiency of the transmitted signal, influencing the quality and clarity of the received information. In amplitude modulation (AM), a higher modulation index can lead to better signal strength but may result in distortion if exceeded. Overall, understanding and controlling the modulation index is essential for optimizing communication performance.
Which require higher bandwidth FM or AM and why?
Frequency Modulation (FM) requires higher bandwidth than Amplitude Modulation (AM) due to the nature of how each modulation method encodes information. FM varies the frequency of the carrier wave to transmit information, which results in a wider range of frequencies being occupied. In contrast, AM varies the amplitude of the carrier wave, which occupies a narrower bandwidth. As a result, FM typically requires about 10 times more bandwidth than AM to accommodate the greater frequency deviations used in the modulation process.
What are the contrast of amplitude modulation to frequency modulation?
AM (Amplitude Modulation) has a smaller bandwidth and can have more stations available in any frequency range. AM is cheaper and can be transmitted over long distances. FM (Frequency Modulation) signals are prone to interference due to physical obstructions. The better sound quality is due to a much higher bandwidth, using FM.
What is the channel bandwidth for 2KHZ signal?
depends on type of modulation and other variables
How is the bandwidth allocated in case of FM?
In Frequency Modulation (FM), bandwidth is allocated based on the modulation index, which is determined by the frequency deviation of the carrier signal and the frequency of the modulating signal. According to Carson's Rule, the total FM bandwidth is approximately twice the sum of the maximum frequency deviation and the maximum frequency of the modulating signal. This means that FM signals can occupy a wider bandwidth compared to Amplitude Modulation (AM), allowing for better noise immunity and audio quality. Typically, for standard FM broadcasting, the bandwidth is around 200 kHz.
What will give vestigial type modulation?
Vestigial type modulation (VSB) is achieved by modifying amplitude modulation (AM) to improve the efficiency of bandwidth usage, particularly in digital television broadcasting. It involves filtering the transmitted signal to eliminate one sideband and part of the carrier, which reduces bandwidth while preserving the ability to recover the original signal at the receiver. This technique helps in minimizing interference and allows for more efficient spectrum utilization. VSB is commonly used in ATSC (Advanced Television Systems Committee) standards for digital TV transmission.
How do you find the bandwidth of 1066 MHz?
To find the bandwidth of a 1066 MHz signal, you first need to understand that bandwidth refers to the range of frequencies a signal occupies. If you have a specific signal operating at 1066 MHz, its bandwidth can be determined by analyzing its modulation scheme or the specifications provided by the manufacturer. For example, if it's a data bus with a specific modulation technique, you may find the bandwidth in the technical documentation. Generally, the bandwidth is the difference between the upper and lower frequency limits related to the signal.
The relationship of the bandwidth required for double-sideband emitted carrier AM to the bandwidth of the modulating signal of?
In Amplitude Modulation (AM), specifically in the case of Double Sideband Suppressed Carrier (DSB-SC) or Full Carrier (DSB-FC) AM, the required bandwidth is twice the bandwidth of the modulating signal. If the modulating signal has a bandwidth of B Hz, the bandwidth required for AM would be 2B Hz. This is because both the upper and lower sidebands of the carrier wave are utilized in the modulation process, each consuming bandwidth equivalent to the original signal.
