Average current and average voltageA full-wave bridge rectifier circuit with a 1-kohms load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer having a single secondary winding. It uses four diodes, each of which can be modeled to have a 0.7-V drop for any current. What is the fraction of a cycle that each diode conducts? What is the average voltage across the load? What is the average current through the load?
Define static electricity and State five sources of static electricity and Describe three methods used to reduce hazards due to static electricity
Consider a chip design using 10 mask levels. Suppose that each mask can be made with 98% yield. Determine the composite mask yield for the set of 10 masks.
What is the maximum bandwidth of the low pass filters at the receiving end of the link? What bandwidth would you recommend for the LPFs?
Why Can Discrete-Time FIR Digital Filters be a Linear Phase, Why can discrete-time FIR digital filters be made exactly linear phase, whereas IIR digital filters cannot?
A sinusoidal voltage with a peak-to-peak value of 15 v is applied to an RC high-pass filter. If the reactance at the input frquency is zero
Detailed Explanation to Op-Amp, A certain op-amp has an open-loop voltage gain of 100,000 and a common mode gain of 0.2. Determine the CMRR in dB.
Calculating a DC Current through the telephone handset, A telephone handset has a resistance of 600 ohm. It is connected to the local telephone exchange at a distance of 5 km by a twisted pair that has a loop resistance of 200 ohm per km
Assume a CDMA system has only 4 walsh codes. If the mobile is assigned W4 and receives a data stream of 11011010, what is the output?
Suppose that we wished to match an admittance using a double-stub tuner where the stubs are lambda/4 apart. For what range of admittance values can
What are the two possible frequencies to which the local oscillator could be set? What bandwidth should the 10.7 MHz IF amplifier have?
Evaluate the TL parameters. Include the effect of the earth as ideal. Do not incorporate the effect of the shield wires.
Measurements show that for a particular arrangement of the equipment and at a particular amplifier setting, the system will howl if 1% of the output power is fed back to the microphone. Estimate the power gain of the P.A. amplifier in decibels.
