4.What is the fundamental benefit of PLC controls over manual controls 5.Describe the differences between the two methods of scanning during PLC logic solving. Which method holds the advantage over the other
The system uses a 7-cell reuse pattern. If the offered traffic per user is 0.03 Erlangs and the average number of calls per hour per user is 1.5, for an Erlang-C system with a probability of delaying a call being 5%, calculate the traffic load per..
Using MultiSim (I am somewhat familiar with this program), connect the circuit drawn in Step 1 using AND gates, NOR gates, and inverters. Connect a logic switch to each input and an LED monitor to the output.
Determine the maximum and minimum spectral frequencies received from a stationary GSM transmitter that has a center frequency of exactly 1950.000000 MHzassuming that the receiver is traveling at speeds of.
Calculate the minimum PWM frequency for a small permanent magnet DC motor with a time constant of 15 milliseconds.
How do we deal with a L1 cache that is Write-back Write allocate, and the L2 cache, which is a Write-through Write no-allocate?
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be increased or decreased
(a) What is the tension in the coupling between the first car and the locomotive? (b) If this tension is equal to the maximum force the locomotive can exert on the train, what is the steepest grade up which the locomotive can pull the train at 25 ..
The value of the element in the first column is the number of the row. The rest of the elements are equal to the sum of the element above them and the element to the left. When executed, the program asks the user to enter values for n and m.
an amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input noise = 1 mV, output signal = 6.0 mV, and output noise = 1 mV. Find: (a) SNR at the input (b) SNR at the output (c) Noise figure
The duration of a cellular call is an exponential random variable with expected value of 3 minutes. A subscriber makes 120 calls each month. Use the central limit theorem to estimate the probability that the subscriber uses at least 400 minutes.
