Design a Wien bridge oscillator and proof that the bridge attenuetes the operating frequency signal by a third.
Once INIT is negated, Z should remain 0 until X has been 0 for two successive ticks and 1 for two successive ticks, regardless of the order of occurrence. Then Z should go to 1 and remain 1 until INIT is asserted again.
Design a square wave generator that will provide a 4kHz square wave with a positive peak vlaue of +10V and negative peak value of -10V. You may use any number of op amps, resistors, and capacitors in this design.
Draw the circuit diagram of a first-order RC lowpass filter and give the expression for the half-power frequency in terms of the circuit components. Sketch the magnitude and phase of the transfer function versus frequency.
A 660 MW, 25 kV, 50 Hz, 2-pole, synchronous generator havinga synchronous reactance of j1.2Ω per phase, delivers rated output at0.85 power factor lagging. (Assume the windingresistance to be negligible).
In a unity feedback system, the open-loop transfer function is of the form Gol(s) = k/(1+s/ωp). Calculate the bandwidth of the closed-loop transfer function. How does the bandwidth depend on K and ωp
The two blocks in the figureoscillate on a frictionless surface with a period of 1.7 s. The upper block just begins to slip when the amplitude is increased to 32cm. What is the coefficient of static friction between the two blocks
Determine the output of the system described by the following difference equations with input and initial conditions as specified: y[n]+6y[n-1]-16y[n-2]=3x[n] x[n]=((-1)^n)*u[n] y[-1]=2 y[-2]=-1
design a DSB-SC modulator to generate a modulated signal km(t)cosωct with the carrier frequency fc = 500kHz (ωc = 2π x 500,000). The following equipment is available in the stockroom: (i) a signal generator of frequency 100 kHz; (ii) a ring modula..
A differential band brake is used to control the speed of a drum. Determine the minimum value of the coefficient of static friction for which the brake is self-locking when the drum rotates counter clockwise.
Write the current form of KCL for the node enclosed by the Kirchhoff surface S1 in the Figure. do the same thing for the surface S2. write down all three forms of KCL for each
Students present a block diagram of the design. Students submit a plan for testing the circuits in order to demonstrate that it meets the specifications.
Two batteries with 1.8 voltage and 10.5 Ohm internal resistance each are connected in series. This battery pack is used to boot a small electric motor with 275 Ohm resistance. Find the power delivered to the motor.
