In the digital communication link the data rate is 500 kb/s. The modulator generates the binary FSK signal.a) Determine the transmitted bandwidth if the difference between two frequencies fc1 - fc0 = 300 kHz, and the transmission shape filter uses the roll-off factor r = 0.5.b) Determine the transmitted bandwidth if FSK modulation to be changed to MSK modulation scheme .
The current in a 20 mH inductor is known to be i = 40 mA, t 0.
The amount of heat Q needed to turn a mass, m, of room temperature ( T_1) water into steam at 100 Celcius. ( T_2) can be found using the specific heat, c, of water and the heat of vaporization, H_v, of water at 1 atmosphere of pressure.
A liquid level system converts a 4-10 m level into a 4-20mA current. Design a three mode controller (PID im assuming) that outputs 0-5 volts with 50% PB, 0.03 min integration time, and 0.05 min derivative time. Fastest expected change time is 0.8 ..
(1) What would an amplifier with a gain of less than 1 be used for (2) (a) Do you think that the inverting amplifier is better than the non-inverting amplifier (b) Is there an advantage of using one versus the other (c) Does it matter
Design a low pass filter with a single op amp, maximum gain of 40 dB, and a corner frequency of 60 Hz. Assume that the input signal has a maximum source resistance of 100 W and you want the error in the gain the pass band
A linear-phase FIR filter should be designed with the ideal magnitude response shown in Figure 1 which represents an narrow band-pass filter. The lower cutoff frequency, fL , is 2,000 Hz, and higher cutoff frequency, fH , is 3,600 Hz.
A 1 A diode can deliver 1 A up to 75ºC with a derating factor of 8.5 mA/ ºC (this means that the current must be reduced by 8.5 mA for each degree above 75ºC). How much current can be drawn at 110 ºC
I have a 3.6V battery, a shottky diode with a voltage drop of 0.22V, and an LED rated at 3V and 100mA. How much resistance will I need. Do i subtract battery voltage - LED voltage and divide by current desired
The equipment works in reception mode, 24 hours a day and throughout the year. About 120 daily Call Ringtone, a median time of 3 min duration each, except Saturdays and Sundays, which are carried out almost no calls are carried out.
A NEMA design B, 3-phase, 60 Hz, Induction motor is rated: 60 HP, 460V, 71A, 93.0% efficiency, NEMA code G, 1180 RPM: A. What is the power factor of the motor B. What is power factor of the motor when operating at 1/2 load
Using MultiSim (I am somewhat familiar with this program), connect the circuit drawn in Step 1 using AND gates, NOR gates, and inverters. Connect a logic switch to each input and an LED monitor to the output.
A 120volt, 60Hz single phase load of 3.2KW with an inductive power factor of 8.1 needs to be corrected to a power factor of 0.95 (inductive). What capacitance value (in uF) is needed
