1. What is an ideal op amp? Compare the properties of a 741C to those of an ideal op amp.
2. Draw an op amp with an input voltage step. What is slew rate, and why is it important?
3. Draw an inverting amplifier using an op amp with component values. Now, tell me where the virtual ground is. What are the properties of a virtual ground? What is the closed-loop voltage gain, input impedance, and bandwidth?
Derive conservation of energy for the pendulum without damping using the slope field equation. - Derive conservation of energy for a general conservative system using the slope field equation.
A load consists of a resistance R in parallel with a capacitor of reactance X. The load is fed from a single phase supply through a line of impedance 8.4 + j11.2 ohms. The rms voltage at the load terminal is 1200 at 0 degress V rms,
Design a logic circuit to control electrical power to the engine ignition of a speed boat. Logic output I is to becomehigh if ignition power is to be applied and is to remain lowotherwise. Gasoline fumes in the engine compartment present aserious ..
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
A zener regulator circuit has a load resistance that varies between 470 ohms and 2700 ohms. The circuit uses a 10V zener diode, Rs = 330 ohms, and the source voltage is 24V. The zener resistance is 10 ohms and the zener test current (Izm) is 28mA.
Design a full subtractor, that is a circuit which computes a-b-c, where c is a borrow from the next less significant bit. (Hint: Denote the difference as d, and a borrow from the next more significant bit as p, then develop a truth table for the p..
Can the motor be used?
Energy per unit length. A line of charge with line charge density PI is surrounded by a dielectric layer as shown in Figure 4.80. The permittivity of the layer is ε. Calculate the energy per unit length stored in the cylinder (a ≤ r ≤b.
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.
Filling of gas bottles is a part of a product line where the bottles are moved by pneumatic cylinders- Draw the position-sequence diagram. What kind of switches would you use (signals from actuators). So what is a type of the switch?
Create 2 equations with 2 unknown variables. For example, one equation would be ax + by = c and the other equation would be dx + ey = f where x and y are the variables and a, b, d, and e are coefficients for the variables and c and f are numbers.
While troubleshooting a power supply, you find a resistor burned black. A measurement shows that the resistor is open. Should you replace the resistor and turn the supply back on? If not, what should you do next?
