Waves and Strings: compute the tension in the top string (i.e. E string, lowest note) of a properly tuned guitar. You will likely need to spend a couple minutes on the internet to obtain length and any other important properties of the string. Perform the same calculation for the bottom string of a guitar. Present your results in both Newtons and lbs. Comment on whether your computed results seem reasonable.
Consider a satellite communication link with a one way propagation delay of 300ms between the sender and receiver, operating at 10Mbps using packets of length 1500bytes. Length of the ACK packet is also 1500 bytes.
A half wave dipole antenna is operating in air at a frequency of 100 MHz. At a distance of 1000 km and at an observation point ? = ?/2, electric field strength is measured to be 5 µV/m. Calculate the a. Length of the antenna
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
A series-resonant RLC circuit has R = 80 (ohms), L=25mh, and C=10pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a minimum D) What is the magnitude of the impedance at this frequency
design and implement an access control circuit for my research lab. There are two inputs - a key card swipe on the door that produces an ID in the 0.7 range, and a day/night sensor that is 1 during the day, and 0 at night.
50 kg of a certain gas is contained within a piston-cylinder assembly. the gas undergoes a processwhich the pressure volume relationship is PV = constant. (n=1.5) the given conditions as follows : p1= 6 bars, v1=0.2 cubic meters ,and v2= 0.4 cubic..
Draw a relay construction diagram and briefly explain the operation of a relay.
Interface TTL logic to 120 VAC lamp. In this part of the lab, you will interface lowpower solid state electronics to the "outside world" by switching the 120 VAC lamp on and off using the AND gate from the previous experiment.
Two free particles (that is, free to move) with charges +1µC and +3µC are a distance L = 2m apart. A third charge is placed so that the entire system is in equilibrium. Find the location, magnitude, and sign of the third charge.
A voltage source v(t)=t*sin(t) is connected to a capacitor with C= 2 farad. Find the energy stored in the capacitor from t=0 to t=1 second.
Power Electronics: A Single-Phase Bridge Rectifier, A single-phase bridge rectifier has a purely resistive load R=10 Ohms, the peak supply voltage Vm=170 V
A collector modulated transmitter has a supply voltage of 48 V and an average collector current of 600 mA. What is the input power to the transmitter. How much modulating signal power is needed to produce 100 percent modulation.
