Q. Aconical horn has a side viewas shown in Figure The maximum value ofthe directive gain is given by GD ∼ = 5.13(D/λ)2, where D =√3.33λL1 and L1 = L/(1-d/D),in which d is the inside diameter of the waveguide. Beam widths for the main beam directed along the z-axis are given by θB = 60λ/D in degrees in the yz-plane, and by φB ∼ = 70λ/D in degrees in the xz- plane. Let the circular waveguide, with a 2.5-cm inside diameter, be expanded by adding a conical ?are to have an aperture with an inside diameter of 5.771λ at 8 GHz. For L1 = 10λ, find:
(a) The horn length L.
(b) The directive gain.
(c) The principal-plane beamwidths.
Q. What is Idss. What are the conditions for its maximum value? The term 'Idss' refers to saturation condition of the Drain current. From the above graph it's clear that as the
If the message has a spectrum where K and Wf are positive constants, sketch the spectrum of a standard AM signal that uses the message. Comment on the physical signi?cance
Boost Converter The boost converter has its output voltage always greater than input voltage like a buck converter boost converter has two modes.
In the circuit shown below, the capacitor initially has a voltage across it 4 Volts (at t = 0). a. Write down the expression for V C (t) when the switch is closed. b. Writ
