IST 7040 Week 2 Discussion

Elaborate on the role of ferrite beads in cable design and their impact on signal quality.

Describe the characteristics of fiber-optic cables as a transmission medium. Explain the advantages of using fiber-optic cables over traditional copper cables.

Discuss the properties of optical fiber cables and their advantages over traditional copper-based cables.

Phase shift due to finite length of circuit conductors. On a particular type of circuit board, assume a signal travels at 2/3 of the speed of light. Suppose a high-speed system using this type of board can tolerate a phase shift in a sine-wave signal due to propagation delay of only 15° before failing to work. Calculate the maximum length /MAX (in m, or a suitable subdivision such as cm or mm) that a circuit-board trace carrying this signal can have at each of the following frequencies without encountering excessive phase shift due to the propagation delay along the trace: (a) f=10MHz, (b) f=30MHz, (c) f=500 MHz, and (d) f=2.5 GHz.

Q8 - You wish to end up with a 2um width metal line (measured at the top of the metal lead cross section). A) You are using an isotropic wet etch process on a 1um thick metal layer. What linewidth should the protective photoresist line be to get these results? Sketch the resulting structure before photoresist strip. B) now you are using a completely anisotropic etch, what is the requisite linewidth of the photoresist to achieve the same end goal? Sketch the resulting structure before the stripping of the photoresist.

Could you please go more in depth about how to create the ac equivalant model? thank you

What is the purpose of the cladding layer in an optical fiber?

A certain microstrip line has fused quartz (er = 3.8) as a substrate. If the ratio of line width to substrate thickness is w/h = 0.8, determine The effective relative permittivity of the substrate %3D

Modern digital spectra are represented by graphing   a. velocity vs. time.   b. intensity vs. wavelength.   c. temperature vs. luminosity.   d. luminosity vs. time.   e. none of these.

What are the advantages of switching from copper to fiber optics as a transmission medium?

2.20 Consider a fiber with a 25-µm core radius, a core index n = 1.48, and A= 0.01. (a) If 1= 1320 nm, what is the value of Vand how many modes propagate in the fiber? (b) What percent of the optical power flows in the cladding? (c) If the core-cladding difference is reduced to A= 0.003, how many modes does the fiber support and what fraction of the opti- cal power flows in the cladding?
