  84) Arrange the following system types in ascending order of their intersection with 0 dB axis.   A. Type N system   B. Type 3 system   C. Type 2 system   D. Type 4 system  Choose the correct answer from the options given below  1. A, D, B, C [Option ID = 3165]  2. C, B, D, A [Option ID = 3166]  3. C, B, A, D [Option ID = 3167] 4.  D, C, B, A [Option ID = 3168]  Answer: A Control Systems: Bode Plots and System Types This question involves understanding how the System Type affects the magnitude plot on a Bode diagram, specifically where it crosses the 0 dB axis (Gain Crossover Frequency). 1. What defines "System Type"? The "Type" of a system is defined by the number of integrators (poles at the origin) in the open-loop transfer function G(s)H(s) . This determines the initial slope of the magnitude plot. System Type Ini...

82) Arrange the following antennas in ascending order of their radiation resistance. Short dipole (L = λ/10)(I av = I o ) Short dipole (L = λ/10)(I av = I o /2) Linear λ/2 dipole (sinusoidal current distribution) Small Loop (square loop) single turn of(L = λ/10) Choose the correct answer from the options given below B, D, A, C [Option ID = 3157] C, B, A, D [Option ID = 3158] D, B, A, C [Option ID = 3159] B, D, C, A [Option ID = 3160] Answer: 1 To understand the fundamentals behind this, we need to look at the formulas for Radiation Resistance (R rad ) of different antennas. R rad represents the equivalent resistance that would dissipate the same amount of power as the antenna radiates. 1. Fundamental Formulas Short Dipole (Length L &ll; λ): The radiation resistance depends heavily on the current distribution along t...
