2. About amplifiers:
(i) Draw/Project a circuit using an operational amplifier with gain
-100
(ii) What is the cutoff frequency of the amplifier in question (i)
if we used an operational amplifier 741?
(iii) What configuration (inverter or non-inverter) is most
vulnerable to finite CMRR ( Common Mode Rejection Ratio )?
(iv) Draw an instrumentation amplifier and calculate its literal
equation of the gain
What is the maximum charge on a capacitor in an RC
circuit?
As the capacitor in an RC circuit charged, what is the current
as a function of time?Explain your answer physically.
1.5 V batteries are usually connected in series. Would the
batteries last longer or shorter if they were connected in parallel
instead?
Design a circuit where the voltage across the capacitor matches
the input step function as closely as possible. Sketch/show a
picture of your result and which circuit parameters (R and C you
used). Explain why the output looks like it does.
Design a circuit where the voltage across the capacitor looks
like a triangle wave (each peak looks like a triangle). Sketch/show
a picture of your result and which circuit parameters (R and C you
used). Explain why the output...
Suppose that you design an amplifier circuit but measuring the
output on the oscilloscope shows that it is just oscillating
wildly. List the first three things to check to understand what is
causing the oscillation.
design an electro- pneumatic circuit with three
cylinder output .the process will be in sequence the cylinder 1
extend , cylinder 2 then cylinder 3(using Timers). draw the
pneumatic circuit including directional control valve and cylinders
etc.. draw the electric circuit of pneumatic circuit including
switches, relays , timer etc..
if possible include the conveyor motor in
electric circuit.
1) design a circuit that output is generated based on the
control signals
Inputs are A1, A0 and B1, B0
C1 C0 Output
0 0 add
0 1
subtract
1 0 AND
1 1 EXOR
2) Design a 5 by 32 decoder using 3 by 8 or smaller decoders
2. You are an engineer trying to design a capacitor. You have a
parallel-plate capacitor made of two circular metal plates. The
radius of each plate is 1 m and they are separated by a distance of
0.1 mm. If the space in between the plates was filled with vacuum,
the capacitor would have a capacitance of 0.278 μF but you want to
make this capacitor have a capacitance of 1.0 μF. You only have
paraffin (K=2.2) and glass (K=5)...
