A load operating at 2300 V rms draws 28 A at a power factor of 0.812 lagging. Find (a) the peak current in amperes; (b) the instantaneous power at t=2.5 ms assuming an operating frequency of 60 hz; (c) the real power taken by the load.
3)what is its frequency content 4) The 1D rect function has a width of 1; i.e. has a non-zero value between +1/2 and -1/2. What is the width of the delta function 5) What is the area of the delta function
Design a circuit to provided a positive voltage whose magnitude is equal to the acceleration (revolutions pre minute) of the wheel. Assume the velocity sensor's output 1 mV/rpm, and the wheel rotates at less than 3500rpm.
A given signal f(t) is multiplied by this periodic signal. Determine an expression describing the spectrum and the time waveform of the resulting amplitude-modulated signal if all componets except those centered at + Wc
How long will the cassette tape player operate at normal power? A walker's cassette tape player uses 4 AA batteries in series to provide 6V to the player circuit.
A "Clock" pulse for a flip-flop could be generated by manually filpping a switch from 0 to 1 and then back to 0. but switches such as those on the logic designer "bounce" when switched from on state to another.
A certain two-terminal circuit has an open-circuit voltage of 9V . When a R = 225-r load is attached, the voltage across the load is 7V . Determine the Thevenin resistance for the circuit.
Problem 1: It is desired that an Arduino along with an EduShield be used to control 6 camerassimultaneously. Each is made by a dierent company: a Canon, a Nikon, an Olympus, a Pentax,a Sony, and a Minolta.
An optical signal from a modulator can be sent to multiple channels by the LCSLM. This; however, requires that the beam size from the AM is adjusted to match the size of the SLM area. Assume that both lenses in an AM setup are identical
A radio link receiver has a signal sensitivity of 100 milliwatt. The SNR required is at least 14 dB. Which is the maximum noise allowed in the receiver.
derive a general formula for percent clipping of a unit amplitude sinusoidal test signal; this is the percent of time during one period in which the signal is clipped. The formula includes peak sinusoidal voltage Vp that would appear at the ouput
1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms. 2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
You will need to go to a manufacturer's website (ex: Motorola) to get the datasheets. The specifications for the different kinds of diodes vary. Copy all of the specifications for each diode as well as all of the specification definitions.
