Determine the impulse resonpse of the Fourier Transform for a moving average filter which produces the average value of the present and previous nine samples of a signal, i.e. averaged over ten samples
A particular load has a pf of 0.8 lagging. The power delivered to the load is 40 kW from a 220-V rms 60-Hz line. What value of capacitance placed in parallel with the load will raise the pf to 0.9 lagging
In an ideal diode, once it is conducting in the forward direction, the voltage across the diode remains constant no matterhow the current throught it changes. a) What is the effective resistance of an ideal diode when itis conducting in the forward..
What is the PIV required of the diode? A half-wave rectifier employing a 12-V-rms 60-Hz sine-wave source and no dc load is filtered using a polarized electrolytic capacitor having a small leakage current.
Assume that a resistor depicted by a color code of Brown, Black, Orange (1%) is connected to the +15 V and AGND terminals of MyDAQ. And assume that the Digital multimeter of MyDAQ shows the voltage drop across the resistor is 15 volts.
A second-order system is being designed. It is desired that the percent overshoot be between 10 and 20 percent. Using the relationship between percent overshoot and damping ratio, this corresponds roughly to zeta being 0.45 and 0.6.
A rectangular waveform has a 50% duty cycle (high for 1/2 acycle and low for 1/2 a cycle). It goes between two voltage levelsof -3 V (low) and +8 V (high), and has a period of100μs. a. Determine the Average voltage of this waveform.
A serial parity bit generator is a sequential circuit that does the following: It receives an N-bit message followed by a zero (so there are N+1 clock bits to send the message). At the output the circuit sends the original N-bit message but replac..
Calculate the load voltage, the load power, and the efficiency of the transmission system under the following schemes. a. 4:1 transformer at generator b. 4:1 transformer to load c. 1:4 transformer at the generator and a 16:1 transformer at the loa..
What is the data rate of a digital electrical communication system that uses 16 voltage levels to carry multiple bits with one voltage level, where each voltage level is kept at that level for a duration of 2 ms
