1) A 2-MHz carrier is modulated by a music signal that has frequency components from 20 Hz to 8 kHz. Determine the range of frequencies generated for the upper and lower sidebands of AM signal.
2) An unmodulaed carrier is 300 Vp-p. Calculate %m when its maximum p-p value reaches 400, 500, and 600V of AM signal.note that modulation percentage is m% = Ei/Ec * 100% where Ei is peak amplitude of the intelligence signal & Ec is peak amplitude of the carrier signal
Design a tunk circuit with resonant frequency of 10 kHz and bw of 500 Hz. show your design equation, then use a circuit simulator package to prove your design is correct. you must attach both your design calculation and computer output.
Design a high-pass op amp filter with a high-frequency gain of -100 and a cutoff frequency of 1kHz. Resistors with values of 1kohm, 10khom, and 100kohm are available. Determine the capacitance and resistance values of the filter.
In a 60-HZ, 208 V (line-line, rms), 5-kW motor, R'r = 0.45Ω and X'tr = 0.83Ω. The rated torque is developed at the slip s = 0.04. Assuming that the motor is supplied with rated voltages and is delivering the rated torque,
A unipolar 16 bit ADC measures 0 - 10 volts full scale. What is the minimum resolvable voltage What is the percent quantization error What is the percent quantization error if a 1 volt max signal is input
Study code acquisition in frequncy hopping spread spectrum communication systems.Describe and explain why it is necessary.Design and demonstrate a code acqusition method.
Given an AC input voltage of Vrms = 200Vrms and a sinusoidal frequency of omega = 120pi rad/sec, determine the following: V1peak (peak value of AC input voltage) V1(peak-to-Vpeak )(peak to peak value of AC input voltage) Frequency of input voltage V..
Summarize when and why it is important to use the "50 O" termination setting on the function generator (with the corresponding 50- O terminator in your circuit, of course). In which situations would this not be necessary
Suppose you need an 8-bit counter, and an 8-bit shift register. How would you go about creating these. Could you create them using the counter and shift register you created already.
A sound wave with an intensity level of 80.9 dB is incident on an eardrum of area 6.00 times 10-5 m2. How much energy is absorbed by the eardrum in 3.0 minutes
a square wave of 1000Hz is introduced into an ideal band passfilter (bandwidth = 100Hz) that is tuned to 5000Hz. The signal output has an amplitude of 0.1V. The filster is thenreturned to 9000Hz.
Sketch a set of iD-vDS characteristic curves for an NMOS Transistor operating with a small vDS. Let the MOSFET have k = 5ma/V^2 and Vt = 0.5V. Sketch and clearly label the graphs for VGS = 0.5,1.0,1.5,2.0, and 2.5V.
