A p-channel JFET operating at VSG = 0 is connected in series with a power supply V and a resistor R = 10 k. Ithas been found that for V 12 V the voltage across R is constant at 10 V. What are IDSS and VP for this FET?
A dielectric sphere has radius r = 2 and the material inside the sphere has dielectric constant er2 = 4. THe region outside the sphere where r > 2 is free space and the electric field there is E1=(16r+2+8\phi). Find electric field E2 inside the sp..
c) Write the SOP boolean equations as obtained directly from the partial truth table above and sketch a logic circuit diagram for them. d) Reduce the above equations step-by-step into the simplest form that would use only NAND gates.
Two men are sliding a 100-kg crate up an incline. If the lower man pushes horizontally with a force of 500 N, and if the coefficient of static friction is 0.30, determine the tension T which the upper man must exert on the rope to get the crate to..
SR flip flop from D Flip flops, Show how to build a rising edge triggered SR flip-flop using a rising edge triggered D flip-flop and combinational logic.
If a signal is digitized at a sampling rate of 20kHz centered at 10 kHz, at what frequency would a signal at 22 kHz appear
During four consecutive clock pulses, a sequence of four values of the x signal is applied. Derive a state table for the FSM that produces z = 1 when it detects that either the sequence 1001 or 0111 has been applied; otherwise, z = 0. After the fo..
Suppose f=20kHz and linear quantization is adopted. Calculate the PCM code when t0=10μs, maximum quantization error, the dynamic range, and the best and worst signal to quantization noise voltage ratio.
Consider the message signal m(t) = 20 cos(2πt) and the carrier signal c(t) = 50 cos(100πt). Write down the AM signal, and sketch the resulting AM signal waveform for 75 percent modulation.
The floor causes couple moments Ma =60 Nm and Mb =35 Nm on the brushes of the polishing machine. What force F is required by the operator so that the resultantmoment on the polisher is zero. Set a = .3 m.
A 10-mV signal source having an internal resistance of 200 kO is connected to an amplifier for which the input resistance is 20 kO, the open-circuit voltage gain is 2000 V/V, and the output resistance is 1 kO. The amplifier is connected in turn to..
A 440-V, 60Hz, 4-pole, delta connected three phase induction motor has the following parameters in ohms/phase. R1= .3, X1= .9, R2=.6, X2=.9 Rc=150, Xm=60 If the rotational losses are 6% of the developed power A.) determine the efficiency when i..
