the handheld in the previous question uses a microcontroller with a 12bit address bus. The memory chips selected have a size of 4K4 bits. If the handheld device is to have a maximum amount of addressable memory, how many memory chips are required per device

Explain the Management of agricultural remote sensing big daTA?

How many range gates does a radar have that uses a pulse width of 4.0 usec and a PRF of 740.0 Hz in use. B) What statistical measures characterize a high accuracy, low precision series of measurements? 1) The standard deviation is high, but the mean is very close to the true value. 2) The standard deviation is very small and the mean is very close

sume a microgrid with an inertia constant of 1.4 seconds (i.e., the value of H). Assume the total generation torque is 1.00 pu, but a fault has caused the total load torque to drop to 0.98

Describe the phenomena that must occur when constructing an overloaded P type doped and N type doped Si structure junction. (give information about concepts such as charge distributions, electric field, and potential different ?

. A 3-phase, 400 V synchronous motor having a power consumption of 50 kW is connected in parallel with an induction motor which takes 200 kW at a power factor of 08 lagging. (i) Calculate the current drawn from the mains when the power factor of the synchronous motor is unity. (ii) At what power factor should the synchronous motor operate so that

A factory load consists of the following : (i) an induction motor of 150 h.p. (1119 kW) with 07 p.f. lagging and 80% efficiency ; (ii) a synchronous motor of 100

a lighting load of 50 kW. Find the annual electric charges if the tariff is Rs 100 per annum per kVA maximum demand plus 7 paise per kWh; assuming the load to be steady throughout the year.

circuit must detect a 01 sequence. The sequence sets z= 1,which is reset only by a 00 sequence. For all other cases, z = 0. Overlap is allowed in the sense that the second bit of the reset sequence 00 can be counted as the first bit of the next set sequence 01. For example, for input sequence x as follows, the corresponding output sequence z would
