Repeat Prob. 3.100 for a full-wave bridge rectifier circuit. Draw the circuit
Problem 3.100
A 2800-V, 2-A, dc power supply is to be designed with a ripple voltage ≤ 0.5 percent. Assume that a half-wave rectifier circuit (60 Hz) with a capacitor filter is used.
(a) What is the size of the filter capacitor C?
(b) What is the minimum PIV rating for the diode?
(c) What is the rms value of the transformer voltage needed for the rectifier?
(d) What is the peak value of the repetitive current in the diode? (e) What is the surge current at t = 0+?
In a CDMA system the chip duration is 0.26us and maximum excessdelay 1.3us, into how many delay bins do the multipath components fall if the maximum excess delay is 100ns is the CDMA system narrowband or wideband
From a high-level perspective, what is the major difference between the LM324 and the LF347. Which of the performance characteristics are significantly different because of this.
A galvanometer has 25 divisions in full scale. Its sensitivity (k) is .2mA/div and resistance (Rg) is 50 ohms. Construct voltmeter using the galvanometer and a 2950 ohms resistor, how will you use the resistor (series or parallel to galvanometer)
Develop the circuit corresponding to Illustration 182 and carry out the comparison of PM and FM yourself.
The unused states have to be taken care of in such a way that Even numbered unused states will go to state 7 and Odd numbered states will go to state 3. The combinational logic portion of the circuit should use NAND and NOT gates only.
Consider a 4-bit counter made with JK flip-flops with preset and clear inputs. Describe the changes/additions that need to make the counter reset after counting to 1001. Be sure to state any assumptions that are made.
Show and explain how you could make a 2-bit counter that will count up or down on an external control signal. Explain the difference between the input and output times.
Suppose L=25mH, but the resistance value,R, is not specified. Find a condition on R so that the circuit is strictly BIBO unstable (i.e., not even marginally stable). Hint: you might not be able to purchase such a resistor at Radio Shack
What maximum current will be drawn from the 5V output of a peripheral device connected to an HCS12 input port. What input resistance does this represent.
Determine the output resistance of the circuit in Fig. 7.19(a) and compare the result with that in the above example. Assume M1 and M2 are in saturation.
f(t) = A[u(t) + u(-t/2-5)-1], where u(t) is the unit step function. Is the energy of this signal finite? Why or why not. If it exists, find the energy of this si
