2. Two impedances Z1 = 300 - j50 Ω and Z2 = 450 + j100 Ω are connected in parallel. Find the equivalent impedance of the pair.
3. A 100-mH inductor and a 100-Ω resistor are connected in parallel. The circuit is excited by a voltage source with vS(t) = 10 cos (1 kt - 45°) V. What is the steady-state current iS(t) flowing from the 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 3,8,12 or 15, the binary output value is one less than the input value, otherwise it is one greater than the..
What should be the capacitance of a capacitor, in series with a 250-ohm resistor, that will limit the current to 1.2 A when the circuit is connected to a 600 V 60-cycle source
Find the output force (from the large piston) when the input force is 10 lb.
if the DFTs are computed using a radix- 2 FFT algorithm. Use this formula to determine the minimum value of N for which the FFT method requires fewer real multiplications than the direct evaluation of the convolution sum
An input signal of 10 sin (2pi 1592t+0degrees) is applied to a series RC circuit with resistor R =1000ohm and capacitor C= 0.1 uF. The current flow through the capacitor is a. 10mApk angle 90 degrees b. 5mApk angle 45 degrees
Calculate the smallest area of the RCS pf the target if the transmitters peak power is 1MW, frequency =10GHz, sensitivity ofthe receiver is -100dB/W, antenna gain is 50dB. Perform the calculation for the reference condition.
If the numerical value of availability represents the amount of energy within a system that can be converted into useful work, does this value depend on existing energy conversion technology accessible for use with the system?
Use as few 2x2 MUXes as possible to design the following circuit. Your circuit outputs Z, which is the square root of the input, X if and only if X is a power of two, otherwise, the output Z=0. Assume the following range for X: 0
Build a 4-to-1 MUX using some tri-state buffers and two inverters(NOT gates). (Hint: you can build a 2-to-1 MUX using some tri-statebuffers and one inverter and then combine several 2-to-1 MUXes tobuild a 4-to-1 MUX.)
To eliminate an interfering frequency of 52 MHz, design a series resonant circuit to be inserted as a shunt. You have available a 10 pF capacitor. Determine the required inductance.
