The practical voltage source is formed by combining an ideal voltage source (Vs) and internal resistance (r).1) Without computing, determine sign of power Ps delivered by voltage source
2)Compute Ps delivered by voltage source3) Compute power Pr absorbed/dissipated in heat by resistor R
4)Compute ratio p=Pr/Ps
5) Find value of R that maximizes p.
6) Assume r << R and compute ratio Pr/PR where Pr is power dissipated by resistor r. Use power balance to determine where power delivered by the voltage source is absorbed
7) Find value of R that maximizes Pr. Compute Pr and p for this value.
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
A full adder is a circuit which adds three bits X, Y, Z together and returns two bits C and S to represent the total as a 2-bit binary number C S. C is the MSB and S is the LSB. For example, if X=1, Y=1, Z=0, the total should be 2, or 102 in binar..
If I created a file name Budget Analysis 2005.html, what would be the short name generated by Windows?
1. What is the difference between On-delay and Off-delay timer instructions 2. How are timer instructions reset What happens when an On-delay timer reaches its preset delay time
The balanced 60Hz waveform sample that we must modulate is the point where t=4.4ms. The DC voltage from rail to rail is 300V. assume the q axis and a axis are in same direction. The use of mathCAD is recommended.
The system contains a door sensor, a window sensor, and a key activation switch. If the switch is on, opening the window will set off the alarm immediately. Opening the door will start a 30 second timer.
Consider a communications channel with a passband of 3 kHz to 27.4 kHz. A modem will be connected to this communications channel and the modem will operate with a signaling rate that is 0.56 the maximum allowable signaling rate for this communicat..
Suppose that the number of customers entering a department store in a day is a random variable with mean of 50 customers/day. Suppose that the amounts of money spent by each one of these customers are statistically independent.
A signal consists of only two sinusoids, one of 45 Hz and one of 25 Hz. This signal is sampled at a rate of 160 Hz. Find the first six positive frequencies that will be present in the replicated spectrum.
Determine the voltage required on the input of the amplifier to give the maximum output of 85 dBuV. If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBuV, calculate the signal-to-noise ratio on the output of the amplifi..
A HCS12 ATD is set to 10-bit unsigned mode. The voltage references are set to ground and 1.0V What is the ADT output for a temperature of 81 degrees The temperature sensor measures 0 to 100 degrees with an output of 10 mV/degree.
Consider the financial aspects of the digital thermometer project. The project cost is estimated at $10,000. The total manufacturing cost of the digital thermometer, as called for in the specifications, total $150(that is, $95 parts
