In designing a low-pass filter for an audio system, the filter stop band attenuation must be at least 40 dB at a frequency that is 2 times the passband frequency. The attenuation in the passband must be less than 1 dB. What is the lowest filter order that will be needed for a Butterworth response?
It is desired to know the design impedence referred to the primary and to the secondary for basic engineering calculations and analysis a. solve for the transformer impedance referred to the primary b. solve for the tranformer impedance referred to ..
a)Write the diffrenece equation for a four-term moving average filter. b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
1. An SEdit schematic showing a properly constructed complex CMOS gate of your function. 2. Annotate the schematic with proper sizing parameters for each transistor to achieve behavior similarto a symmetric inverter
100 kg of a certain gas is contained within a piston-cylinder assembly. the gas undergoes a processwhich the pressure volume relationship is (PV)^n = constant. The initial pressure is 6 bars, the initial volume is 0.2 cubic meters

The maximum ratings for all resistors of this type are 250 (V) and ½ (W). What range of resistance values are limited by the maximum voltage rating of 250 (V), and what range of resistance values are limited by the maximum power of ½ (W)
Draw a state diagram for an FSM (Moore machine) with no inputs and three outputs x, y, and z, where xyz should always exhibit the following sequence: 000, 001, 010, 100, repeat. Make 000 as the initial state.
Two delta-connvected loads are connected in parallel and powered by a balanced Y-connected system. The small of the two loads draws 10k VA at a lagging Power Factor (PF) of 0.75, and the larger draws 25k VA at a leading PF of 0.80.
A series circuit has a DC voltage source (56 volts), a resistor, (72 ohms), a capacitor (82 farads), and a switch. The capacitor is initially uncharged and the switch closes at t=0.
