Create a flowchart and pseudo-code for generating a report that prints all of the movies, with all movies made by the same director on one page, as well as the number of movies by each director.
Next find a 95% confidence interval for the proportion theta of defective chips and also find a one sided 95% confidence interval for the proportion of defective ones. Refering to this problem, how large a ssample should be taken
For a modulating signal) x(t)= (t/T) a) Write an expression for the PM modulated signal. b) Write an expression for the FM modulated signal. c) What is the maximum phase deviation of the PM signal
The Signal power to noise power ratio is an important measure of the transmission quality of any channel. If at the receiver there is a 12 dB signal to noise ratio and the received signal power is 50 micro W then calculate the received noise power..
A three-phase, wye-connected, 220-V, 10-hp, 60-Hz, six-pole induction motor has the following parameters in ohms per phase referred to the stator: R1 = 0.294; R2 = 0.144; Xn = 0.503, X12 = 0.209;XM = 13.25.
Capacitance can be altered by bringing the two wire line close to ground. (a) Apply the method of images to determine the Capacitance of the two-wire line shown in the figure, where the lower wire is suspended a distance from the PEC ground.
A batch process which involves filling a tank with liquid, mixing the liquid and draining the tank, is automated with a PLC. The specific sequence of events is as follows
A 3kw, 120V, 2400 rpm shunt motor has an armature resistance of 0.4 ohms and a shunt field resistance of 160 ohms. The motor operates at full load. The no load current is 2A. If an external resistance of 2.5 ohms is insertions in the armature circ..
