(a) A student would like to find the relative dielectricconstant of a non-magnetic medium. He transmitted a plane EM waveat 10GHz inside the medium and found that the propagating wave hasa wavelength of 1.5 cm. What is the relative dielectricconstant?(b) If the student transmits the same 10GHz wave insideanother medium of characteristic impedance of 200 Ω. Whatwould be the relative dielectric constant and the wavelength insidethis medium?(non-magnetic medium has μr=1)
Determine(using the thevenin equivalent circuit) what size resistor should be placed betweent R4 and R5 to ensure that resistor receives the maximum power possible from the power source
Design a combinational circuit with four inputs, x,y,w, and z, and four outputs: A, B, C, and D. When the binary input value in decimal is 3,5,6,9,10 or 12, the binary output value is one less than the input value, otherwise it is one greater than..
An ac bridge has the following constants : arm AB, R= 1,000Ω in parallel with C=0.159μF; BC, R=1,000Ω; CD, R=500Ω; DA, C=0.636μF in series with an unknown resistance.Find the frequency for which this bridge is in balance and determine the value
A special external data signal (DATA_READY) is asserted whenever each of the bits for X are available. In addition, another special signal (ENCODE) is asserted during the transmission of the data X indicating whether 2X+3 or 3X+1 should be compute..
