What are the disadvantages of DSB-fC modulation?
in DSB-SC since carrier is suppressed,hence power consumption is reduced and nominal.The power in the modulated signal is contained in all four sidebands.The bandwidth of the DSB-SC signal is double that of the message signal, that is, BWDSB-SC =2B (Hz).How many sidebands? There's only two; upper and lower.
What are advantages and disadvantages of digital signal processing and implementation of pulse laser rangefinder?
Digital signal processing (DSP) in pulse laser rangefinders offers advantages such as improved signal clarity, noise reduction, and the ability to easily implement complex algorithms for better accuracy and range measurement. Additionally, DSP allows for real-time processing and adaptability to varying environmental conditions. However, disadvantages include the need for advanced hardware and power consumption, which can complicate portability and increase costs. Furthermore, reliance on digital components may introduce vulnerabilities to software-related issues or malfunctions.
