A piece of wave guide WG16 operating at 10GHz is used to make a wave guide termination by placing a thin resistive sheet at a distance 'd' from the short circuit. Calculate 'd' and the resistance per unit area of the sheet.
The odd cycle sequences1,3,5,7, and repeats. An external input selects which cycle to perform. An input of 0 selects the even cycle and an input of 1selects the odd cycle. The cycles can be entered and exited throughstates 0 and 1.
Design a counter whose count sequence is all prime numbers greater than 4 less than 55. Provide the excitation equations for the FlipFlops.
The signal x(t)=10cos(t)+10sin(10t) is input into the following systems: a) \(H(s)=100/(s^{2}+10s+100)\) b) \(H(s)=s^{2}/(s^{2}+10s+100)\) calculate the output for each system.
The transformer is to be used on a 50 Hz system, with the restriction that it maintain the same maximum core flux and the same total losses. Determine (a) the new voltage rating; (b)the new kVA rating.
The switch in a RC circuit is closed. If the resistance is 134462ohms, the capacitance 7.5 microF, and the applied voltage 18 volts, what is the (average) rate of change of the voltage on the capacitor, to the nearest tenth of a V/s, during the fi..
The motor details are as follows: 1 hp, 10V, 2500 rpm, 78.5 % efficiency, Ra=.01 O, La=.002 H, Kb= .03819 V/rad/sec. The chopper is one quadrant, and the on-state voltage drop across the device is assumed to be 1V regardless of the current variati..
A series circuit consists of a 240V source and 20ohm, 30ohm, and 10ohm resistors. a) Find the current out of the positive terminal of the voltage source. b) Find the voltage across each resistor.
A circuit designer claims this circuit will produce an output voltage that will vary betweeen +5 or -5 as Vg varies between 0 and 5 V. Assume op amp is ideal. A)Draw a graph of the output voltege Vzero as a function of the input voltege Vg for 0=
A ¼ watt resistor has a resistance of 3.2KW what is the maximum current that the resistor can handle. If the wattage rating is doubled, will the maximum current double.
The channel bandwidth for the analog AMP's system is restricted to BW= 30 kHz. Determine the noise floor (in dBm) for its mobile receivers assuming all receivers have a noise figure of 10 dB.
