A small house has three windows and two doors. Each window and door has a switch attached such that the contacts close when a door or window opens. Draw a ladder logic diagram that will turn on a light if one or more windows are open or if both doors are open.
An 1100 V. 50 Hz star connected induction motor has a starconnected slip-rings rotor with a transformation ratio of 3.0. Therotor resistance per phase is 0.015 ohm and leakage inductance is0.8 mH per phase . Neglect stator impedence .
The bandwidth of a series resonant circuit is 400 Hz. (a) If the resonant frequency is 4000 Hz, find Q. (b) If R = 10?, what is the value of XL at resonance (c) Find the inductance L and capacitance C of the circuit.
Using the graph of BER vs CNR for BPSK, estimate the BER in clear air and in the specified rain conditions when no error correction is used, and when convolutional encoding with k = 7 is applied to the transmission. The bit rate is the same in eac..
Using a 500 Ohm resistance, design an RC low-pass filter that would attenuate a 120-Hz sinusoidal voltage by 20 dB with respect to the DC gain.
determine the frequency response and the magnitude response of the z tranfer function below. please show step to step how to get the result. D is a positive interger
calculate the convolution (x1[x]*x2[k]) for the following pairs of sequences: a-) x1[k]=u[k+3]-u[k-2] and x2[k]=u[k+5]-u[k-4] b-) x1[k]=0.5^k u[k] and x2[k]=cos Pi*k u[-k]
A 50-kW 440-V 50-Hz two-pole induction motor has a slip of 6 percent when operating at full-load conditions. At full-load conditions, the friction and windage losses are 520 W, and the core losses are 500W. Find the shaft speed nm for full-load ..
The results of open-circuit and short-circuit tests on asingle-phase, 25kVA 440V / 220V, 60Hz transformer are as follows: Open-circuit test (primary open-circuited, with instrumentation on the secondary side): 220V, 9.6A, 710W.
You deposit 10% of your annual salary at the each of each year in a retirement account. F= Future worth A1= first annual deposit n=number of years g=geometric gradient F=A1(1-(1+g)^n(1+i)^-n/(i-g))(1+i)^n use Matlab to graph the function.
A solid metal cube has a spherical cavity at its center as shown in Fig. 22-28. At the center of the cavity there is a point charge Q = +8.00 µC. The metal cube carries a net charge q = -6.00 µC (not including Q).
Build a C++ code for vehicle sensing device. Code is required to embed in the device so that then it must sense the location where the vehicle is currently present. The device must be able to track the location of the vehicle for its owner
Suppose there is only a single user (i.e., K = 1). From your plot in part (1), do you think the dual transmit antennas provide any gain? Justify your answer. Hint: Use Jensen's inequality.
