For the network of given figure, VL must be 8 V before the system is activated. If the switch is closed at t = 0 s, how long will it take for the system to be activated?
An assembly line can produce 90 units per hr. The line hrly cost is $4500 on stright line ( the first 8 hrs). Workers are guaranteed a minimum of 6 hrs. There is a 50% premiun for overtime (time and a half), how ever productivity drops by 5%.
Analog to Digital Converters The input signals of an (10bits) ADC are from -1Volt to +1Volt. a) What is the rage of the converters b) What is the resolution c) What is the precision What is the value the minimal input signal variation that this ADC c..
suppose that A/D-H(z)-D/A system shown uses a sampling rate of 20000 samples/sec , let xa(t)=10cos (2p*500t)u(t) a- give another input signal x1(t) which gives the same samples x(n) b- give another input signal x2(t)
Find the density for germanium (Ge) semiconductor atoms give that its lattice constant a-5.66Å (Angstrom) and atomic weight is 72.59 g/mole.
Why is it that fuses and breakers do not prevent transformer and cable overloads? What function do fuses and breakers perform?
What is the cutoff frequency ωc for the resulting discrete-time filter?
Assume all that youhave a single 1nF capacitor, any number of op amps,and any numberof resistors. Design a circuit that has a port impedance of1uF.
Design a synchronous 20-to-25 counter using the minimum number of DFFs.
A JFET has the following ratings: gm0 = 4000µs at VGS off ( ) = 6 Volts and gm0 = 2000µs at VGS off ( ) = 2Volts. The component is used in a common source amplifier with values of RD = 3.3 Kohm, RL = 4.7 K ohm,and VGS = 750
Derive the state-space equations of electromechanical systems from first principles. Use Matlab/Oc- tave to represent state-space systems numerically and simulate their response to impulses and steps.
You are to analyze the audio recording and playback system shown below. The input audio frequency range is fÎ[0, 3.5] kHz. The listener's hearing range is fÎ[0, 8] kHz. The ADC operates at the programmable sample rate of fs = n8kHz, n an integer.
A mechanic uses a piece of pipe AB as a lever when tightening an alternator belt. When he pushes down at A, a force of 580 N is exerted on the alternator B. Determine the moment of that force about bolt C if its line of action passes through O.
