Q1. Choose the correct answer: 1. Increasing the amplitude of a square pulse (increases, decreases, maintains not related) the spectrum range in the frequency domain. 2. A continuous FT indicates a signal. (continuous, discrete, periodic non-periodic). the pulse duration is proportional to the amplitude of the signal. (PAM, PWM, PPM, 3. In ASK). . In VSB transmission (both sidebands are used, single sideband is used, single sideband and part of the other sideband, only the vestige of the carrier signal is used). 5. An economic FDM receiver design should contain simultaneous reception, selective reception). 6. In AMI code, the shapes of "1" and "0" are dependent, not related to each other). 7. In FDM the guard band is used to (pilot carrier zero crossing detector, (the same) opposite to each other, next bit increase the overlap between FDM signals, decrease the overlap between FDM signals, increase the baseband bandwidth, decrease the baseband bandwidth). 20 3.

In a railway system with a power source of 600 VDC, I need to achieve a load output of 120 VDC for railway lights. I found a DC-DC converter capable of stepping down 600 VDC to 125 VDC. To obtain 120 VDC from this converter, we can use a voltage divider with the following equation: [R2/(R2+R1)]=120/125=0.96=0.96However, using resistors to achieve the desired output voltage raises some concerns. Is it advisable to use railway-grade resistors for this application? I found some resistors in the range of 1-10k ohms, but I am unsure how they should be connected in the circuit with the lights (the load to be used). I would greatly appreciate any suggestions or schematic diagrams to clarify the best approach for connecting the resistors in this setup.
