In a certain system, an electric heating element was found to increase the temperature of a piece of metal 10° for each ampere of current. The metal expands 0.001 in. /deg and pushes on a load sensor which outputs 1 V/0.005 in. of compression.
a. Find the transfer functions of the three components and draw the block diagram.
b. Calculate the overall transfer function of this system.
The system operates properly when exactly one of the sensors has its output equal to 1. An alarm must be raised when two or more sensors have the output equals to 1. Design the simplest circuit that can be used to raise the alarm. Give the cost of..
Single pole amp. has an open loop gain 10^6 and open loop bandwidth of 10Hz. If the feedback factor =1, calculate the gain and bandwidth after the feedback
The current through a 8 mH coil changes at the rate of 3.5 A/s. Determine the voltage that appears across the inductor. (mV)
A voltage source 100(angle 0 degrees) is in series with a 200 ohm resistor and a cpacitive reactance of -100 ohms. a) What impedance,Zl, in parallel with the capcitor would absorb maximum AVERAGE power
The NF (dB) is defined as 10log(SNRin/SNRout) - in the unit of dB. If we are given the values of SNRin and SNRout in dB unit, how do we calculate NF (dB) in terms of dB, and how do we calculate NF in term of a pure ratio
A phase modulation (PM) signal s(t) has a modulating wave m(t) = Amcos(2ðfmt) and phase sensitivity kp = 10 radians/V. What would be the modulating signal if the same signal s(t) is generated by frequency modulation (FM) with frequency sensitivity..
High-definition television (HDTV) generates images with a resolution of 1125 horizontal TV lines interlaced (where every other line is painted on the tube face in each of two fields, each field being 160th of a second in duration).
Determine(using the thevenin equivalent circuit) what size resistor should be placed betweent R4 and R5 to ensure that resistor receives the maximum power possible from the power source
apply the MACDtrading strategy to the closing price of QQQQ for the period from February 1, 2005 through September 1, 2005. What is the netgain over the time period assuming that your first order must be abuy and your last order a sell
When electros and holes are present in a semi-conductor, the presence of an electric field produced by an external voltage will cause this carries,which have changes of oposite sign, to move in opposite directions.
Develop a system to help students learn Morse Code. The system will have one input and 26 outputs (one per letter). The user sends in Morse Code pulses on the input, and as characters are completed the appropriate letter is lit up momentarily.
Calculate the efficiency of transmission at the IP level. Assume no options for the header and no errors. Calculate the efficiency of transmission at the data link layer. Assume no options for IP header and Ethernet-II format are used at the d..
