Question

1.

(TCO 6) Which of the following transmission lines can be used to transfer signals in the mm wave frequency range most efficiently? O Parallel lines OTwisted pair O Coaxial cable O Waveguide

2.

Answer 1

1) Wave guides are used for efficient transmission of signals in millimeter wave frequencies. All other transmission lines are lossy at higher frequencies. (Answer last option)

2) Quantization interval = Peak to peak voltage / total number of samples.

given V_pp = 2V and

no of bits = 10. So, total number of samples = 2¹⁰ =1024

So, Quantizatio interval = 2 / 1024 = 1.95mV approximately
