One axis of an NC positioning system is driven by a stepping motor. The motor is connected to a lead screw whose pitch is 4.0 mm, and the lead screw drives the table. Control resolution for the table is specified as 0.D15mm. Determine
(a) the number of step angles required to achieve the specified control resolution,
(b) the size of each step angle in the motor, and
[c) the linear travel rate of the motor at a pulse frequency of 2UOpulses per second
Consider a product data sheet for a photo-detector that states an optical power level of -32dbm is need at the photo-detector to specify performance requirement. What is the power level nW (nano Watts)
question 1consider two digital sequenceshere m is a positive integer and is a value in the intervala using the
What is the maximum power dissipated in the load when the Thévenin voltage is 21 V cos(52 rad/s t + 82°), the Thévenin impedance is 102 -j 184 ohm and the load impedance is 102 + j 184 ohm
a thermocouple is a heat-sensing device that typically outputs a signal in microvolts, such as 10 microvolts.if the signal transmitted to the controller needed to be 10 volts, what approximate amplification would the transmitter need to supply
Why does the Thevenin's technique work only for circuits with linear elements (or at most a single non-linear resistor). Figure out where the mathematics of the theorem breaks down for non-linear elements and why
Repeat Example 5.5 and calculate the electric field intensity everywhere in space (not only on the x-y plane) and the charge density on the conducting surfaces as it depends on x, y, and z. Assume the charge q is placed at (a, b, 0).
Assume that a fault occurs on the high-voltage side of transformer T2 in the power system shown in Figure P13-2. Make the assumption that the generator is operating at rated voltage, and that the power system is initially unloaded. Calcu..
determine the minimum sampling rate necessary to sample and perfectly reconstruct the signal x(t) = sin(6280t) / (6280t).
when the bit rate of a message signal from the message sequence generator and the bit rate of a pn code from the
Calculate the speed and the current when the motor field winding is shunted bya divert or of equal resistance as that of the field winding.Neglect all motor losses and assume the magnetic circuit a sunstaturated.
find the received power (in W) if the transmitted power is 100 W, the distance of the dipole from the transmitting and receiving antennas is 100 m, the gain of the transmitting and receiving antennas is 15 dB each, and the frequency of operation i..
