For a single frequency sine wave modulating signal of 3 KHz with a carrier frequency of 36 MHz, what is the spacing between sideband?
Design (simulaton, analysis), build and test an op-amp based instrumentation amplifier with the following specifications: (a) Have very high input resistance (minimum is 1 Mega Ohm). (b) Have very high voltage gain (minimum 1000V)
A carrier signal c(t) = 10 cos(2pifct) is modulated using a message signal m(t) cos(20pit). The modulation is FM, with kf = 50.Write equation for modulated signal What is average transmitted power & modulation index
A certain power amplifier with crossover distortion has the input/output voltage relationship vo (t) = vi (t)3 (2.39) a) Use example voltage values to show that this does not satisfy the relationship. b) Let vi (t) = sin (pi t) .
An address decoder in a 68000-based microprocessor system selects a memory device when the address lines A23, A22, A21, A20, A19, A18 = 1, 0, 0, 1, 1, 0. What is the size of the memory block decoded and what range of addresses does it span
Suppose that an inductor is formed by N turns of a conductive wire wound around a magnetic material. The magnetic material forms a circular cylinder of radius r = 10 cm, and height h = 5 cm. The inductance of the inductor turns of N is defined as:..
A 30-km, 34.5-kV, 60-Hz three-phase line has a positive-sequence series impedance z = 0.19 + j0.34 ?/km. The load at the receiving end absorbs 10 MVA at 33 kV. Assuming a short line, calculate: (a) ABCD parameters,
Design a clock that displays seconds from 0 to 30 on the FPGA 7-segment displays, with a reset button that resets the clock value at any time.
Two statistically independent random variables, X and Y, have variances of sigma^2 (X) =9 and sigma^2(Y) =25. Two new random variables are defined as: U = 3X + 4Y V = 5X - 2Y (a) Find the variances of U and V.
What value of emitter resistor would you choose, if: a) You have to amplify the signal of a microphone that has an internal resistance of 100K using a Common Emitter bias configuration b) you have to drive a load of 50 with an Emitter Follower cir..
Discuss how the angle of the incident light affected the solar cell? How could solar cell designs and/or installations be designed to counter this affect?
Assume we have a toroidal coil with a rectangular cross section, with an inner radius 1 cm, an outer radius 2 cm, a height of 1 cm and 1000 turns. The coil is connected to a resistor of 500 ohms. An AC current I(t) = Io cos(wt)
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.
