Write the magnitude function for a third order Chebyshev filter having a ripple coefficient of 0.4. Do not expand. Also find the cutoff frequency.
A transistor amplifier has a midband gain of -120, a high cutoff frequency of 36 kHz, and a bandwidth of 35.8 kHz. In addition,the actual response is also about -15 dB at f=50 Hz. Write the transfer function for the amplifier.
A 4KHz audio signal is transmitted by using a PCM system and the quantization level, L is 256. Find transmission bit rate.
Show the design of a 2-1 Mux: (a) using a NAND/NAND implementation, (b) using a NOR/NOR implementation. Which would you prefer to build and why Assume that you have all variables and their complements available.
The Fourier transforms of odd and even functions are very important. The reason is that they are computationally simpler than the Fourier transform. Let x(t) = e-ItI and y(t) = e-tu(t) - etu(-t). a. Plot x(t) and y(t), and determine whether they ar..
v(t)=20te^( -40t ) and i(t)=50te^( -40t ) for t>=0 both v and i are zeros for i
The expression for the torque of an induction motor as a function of its slip may be obtained by application of Thevenin's theorem to the circuit model. Show that the Zth obtained can be shown to be approximately equal to Zth = R1+JX1
What are the differences between volatile and nonvolatile memory What are advantages and disadvantages of volatile and nonvolatile memories
Assume that life on Mars requires cell potential to be +100mV, and the extracellular concentrations of the three major species are following (mmol/L): Na+ : 145; K+ : 4; Cl- : 120. Choose one species and assume that other two permeabilities are ze..
Three friends (Al,Bob and Chris) put their names in a hat and each draws a name from the hat.(Assume Al picks first, then Bob,then Chris). Find the sample space. Find the sets A,B,and C that corresponds to the events "Al draws his own name".
1. Provide 3 ways for creating proto-types of an electronic circuit. 2. Explain briefly, in outline form, and in your own words, the procedure for creating a single-sided, PCB (Printed Circuit Board), using the etching procedure.
a. Describe the operation of a typical NMOSFET transistor used both as an amplifier and a switch. b. List the 3 regions of operation and draw the I-V characteristic curve. c. Show the effect of channel length modulation on your graph.
A long solenoid with 11.9 turns/cm and a radius of 5.76 cm carries a current of 18.2 mA. A current of 4.77 A exists in a straight conductor located along the central axis of the solenoid.
