A lossless transmission line, with characteristic impedance of 50Ω and eletrical length of l=0.27λ, is terminated by load impedance 40-j25Ω. Determine voltage reflection coefficient.
Economic formulas are available to compute annual payments for loans. Suppose that you borrow an amount of money P and agree to repay it in n annual payments at an interest rate of i. The formula to compute the annual payment A is
A linear circuit has a capacitance of 1.0 mF and an inductor of 1.0 µH. If the frequency response of the voltage gain should stay the same and the capacitor is scaled to 70 µF, what should the value of the inductor be
b) What are the equilibrium electron and hole concentrations at 300K and 500K (hint: You will have to find Nc and Nv at 500K, but it isnt necessary for 300K) c) Why does the mobile carrier concentration increase at high temperatures
Consider a discrete-time linear time-invariant system with impulse response h[n]. If the input x[n] is a periodic sequence with period N (i.e., if x[n]=x[n+N]), show that the output y[n] is also periodic sequence with period N.
Suppose you want to build a simple RS flip-flop that is set and reset by negativegoing pulses. All you have are two 2-input AND's and two 2-input NOR's. Show how you would build this odd circuit from the available material.
a) The input signal to an amplifier is -20 dBm. What is the input signal power in mW. Given the input signal and noise power in parts (a) and (b), what is the input signal-to-noise ratio in dB.
The circuit generates an output of 1 (0) when the third bit is received if the 3 bits have even (odd) parity; the circuit output is a don't-care for the first 2 bits. Construct an incompletely specified table for the circuit.
Draw a block diagrams showing enamel, address, and data lines for each of the following: 2732, 2764, 27128, and 27256. Draw a schematic for a 6k x 8-bit memory array using a minimum number of 2732's.
(a) If the excitation volatge Eo is equal to the terminal voltage ( 4kv ), what is the maximum real power which the motor can deliver without losing synchronism (b) What is the rotor pole shift in electrical degrees
The length of a wire of a potentiometer is 100 cm, and the e.m.f. of its stand and cell is E volt. It is employed to measure the e.m.f. of a battery whose internal resistance is 0.5 ohm. If the balance point is obtained at l =3..
Discuss why it is important to understand how interpret data from op amp datasheets. How might this skill be used when designing op amp circuits.
A rod on the surface of Jupiter's moon Callisto has a volume of 0.3 cubic meters. Determine the weigh of the rod in units of pounds-force. The specific gravity is 4.7 gravitational acceleration on Callisto is 1.25 meters per second squared.
