1. For the lowpass RC filter, calculate the phase and magnitude ofthe transfer function at frequencies of 20, 50, 100, 200, 500,1000, and 1500 Hz. Tabulate the result and then sketch themagnitude and the phase of the response as function of thefrequency (use log scale for frequency). Use R=50 kΩ, C=0.02μF
2. Determine the half power frequency fc defined as the frequencyat which the magnitude of the transfer function is at 1/√2 ofits maximum value. Assuming C is fixed at 0.02 μF, calculatethe half power frequencies corresponding to R=20 kΩ, 50kΩ, and 100 kΩ.
At the receiver, demodulate the double side band signal S(t) = [cos(90*pi*t) + cos(120*pi*t)] * [cos(400*pi*t)], with the local carrier cos(400*pi*t). Design a low pass filter to suppress the carrier and plot the amplitude spectrum of S(t)
An emitter follower is operating at a collector bias current of 0.25 mA and is used to connect a 10 kiloohm source to a 1 kiloohm load. If the nominal value of beta is 100, what output resistance Rout and overall voltage gain G result
The general expression for an idealized uniform plane water wave propagating in the +x direction is h(x,t) = Acos(wt - kx + phi) m where h represents the height of water particles at the water surface above the unpurturbed or quiescent water surface ..
Compute z in decibels required to give PE = 10-7 for noncoherent, binary FSK and for DPSK. For the latter, carry out the computation for both the optimum and suboptimum detectors.
A circular capacitor of radius r is made using SiO2 as the dielectric on a silicon wafer. If a trench of depth l is made to replace the circular capacitor with the trench capacitor with trench depth l, find the ratio of the two capacitances.
Any flip-flop type can be implemented from another type with suitable logic applied to the latter's inputs. Show how to implement a loadable D flip-flop starting with a T flip-flop.
How do you create a C-style string. Give examples. How do you input or output a C-style string. What kinds of tools are available to work with C-style strings. Show some examples of using those tools.
You must design a three axis position indicator for the latest robot arm. Using no more than two operational amplifiers, design a circuit that uses three inputs, v1, v2, and v3 to produce an output signal vo=3 v1-2 v2-5 v3.
A shopper in a supermarket pushes a cart with a force of 37 N directed at an angle of 25° below the horizontal. The force is just sufficient to overcome various frictional forces, so the cart moves at constant speed.
a coaxial cable can carry signals in the range 50mhz to 450mhz. The bandwidth of cable is divided into a numbe of sub-channels each occupying with the guard band, 40mhz of bandwidth. In each channel the guard band takes up 4 mhz
Calculate the inductance of a solenoid with 125 turns if the length of the solenoid is 18 cm and its radius is 1.6 cm
