A string on a guitar has a mass of 0.730 g and a length of 0.640 m. When played, it produces a sound of 196 Hz. The wavelength of the wave on the guitar string is 1.28 m. A) What is the tension in the string? B) If a speaker is using 25 W of power to produce the sound, what is the intensity level measured at a distance of 5.0 m from the speaker? Assume the speaker emits sound uniformly in all directions
Design a sequential Mealy circuit with two inputs A and B, and output X using JK flip-flops. The circuit produces an output X = 1 when it detects the sequence of either A = 00 or B = 11, otherwise X = 0.
Perform a link budget for a 25-kilometer point-to-point microwave link in the 30 GHz band. Calculate the free space loss (dB), received power dBm), fade margin (dB), and Fresnel zone radius(m) given the following: Tx Power = 70 dBm
Three capacitors are found that each have an impedance of -j2.0, and they are connected in parallel with the load in a wye configuration. Determine the power factor of the combined load as seen by the source.
For a RL circuit, write a diffedrential equation in which the only time dependant quantity is current (use Kirchoff's loop). Derive an expression for current, i(t), in terms of L,R, and Vo. If Vo=5V, R=2.5 ohms, L=100 nH
A square pulse train (i.e. square wave) with low and high voltage values of VL= 0 and VH= 2.9 volts is applied to a DC voltmeter. The voltage measured by the instrument is 0.2 volts. The same signal is applied to an 99 O resistor.
The DC shunt motor is running at full load with a supply voltage of 440 V and a supply current of 70 A. The rotation speed in full load is 1000 rpm, the field resistance is 200 Ohm and the armature resistance is 0.2 Ohm.
Two voltage waves of equal amplitude, V0, and frequency w, propagate in the forward z direction in a lossless transmission line of characteristic impedence Z0. One waves is phase-shifted from the other by \o radians.
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
A one quarter wavelength piece of 75 ohm microstrip line has a capacity load of Xc = 22 ohms. What impedance does a driving generator see
Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
