Suppose you want to move a database from its current location to a new location (and computer) that is three hours driving time away. The data has been copied on to 50 DVDs, each containing 4.7GB of data. What is the effective data rate of this transfer (not counting the time for reading or writing the DVDs)?
A signal y(t) is defined as y(t) = box(t/1.1) * box(t/0.9) * box(t/0.8) * box(t/1.2) where * denotes convolution and the signal box(t) is box(t) = u(t+0.5)-u(t-0.5). -Determine y(1.0) -Determine max(y(t)) -Determine the definite integral of y(t) o..
where H is an A/M and B is in T. If a magnetic circuit contains a 12 cm length of material X, as well asa 0.25 mm air gap, assume a uniform cross section of 2.5 cm2 and find the total mmf (Vm) to produce a flux of
Low-cost audio power amplifiers often avoid direct coupling of the loudspeaker to the output stage because any resulting dc bias current in the speaker can use up (and thereby waste) its limited mechanical dynamic range.
Otherwise determine where any other states will go. Draw a transition tablebased on the state diagram. Design a combinational logic diagram using only NAND gates in addition to the flip flopsand BCD to seven segment display.
Design 3 stage amplifier with the following requirement input signal = 5 mV with R=10k ohms over all gain > 1000 power supply: Vcc = 5V, Vee = -5V Rin > 1 Mega Ohms Rout = 100 ohms 1st Stage BJT must use inverting
A single-phase 240/120 V transformer has the following parameters: R1 = 1-ohm; R2= 0.5 -ohm; X1 =6 -ohm; X2 = 2 -ohm; R0 = 500 -ohm; X0 = 1.5k -ohm.A load of 10 -ohm at 0.8 power factor lagging is connected across the low-voltage terminals of the tra..
Water is flowing out of a tube at a near constant volumetric flowrate, V .If a graduated cylinder is used to collect a certain volume, v , of the water, and a timer is used to measure the time, t, required to collect the volume of water, the volum..
A collector modulated transmitter has a supply voltage of 48 V and an average collector current of 600 mA. What is the input power to the transmitter How much modulating signal power is needed to produce 100 percent modulation
the voltage drops across three resistors in series are measured to be 10.0v 15.0v and 25.0v. if the largest resistor
A three-phase, 400 V system has the following load connected in delta: between the red and yellow lines, a non-reactive resistor of 100; between the yellow and blue lines, a coil having a reactance of 60 and negligible resistance
An embedded system consumes the following current when in different operating modes: Operating Mode Avg. Current Time Data Acquisition 4.2 mA 1.8 ms Communication 22.6 mA 2.5 ms Sleep Mode 0.5A 5 hours
A single phase 220V system draws a current of 15A at a lagging power factor of 0.8. Calculate the value of a capacitor that can be used to improve the power factor of this system to 0.95 lagging.
