What is the minimum sampling frequency to be able to avoid aliasing if your system has 10Hz, 100Hz and 1500Hz mixed in a signal?
A proportional controller for a rotating antenna has a gain Kp of 5 in .oz/deg. The antenna was initially pointing due south but was then commanded to point southeast. a. Find the initial torque supplied to the antenna.
The antenna has a 30 dB gain and has a radiation resistance of 85-ohm. This line is loaded by a matched source TX. The receiver antenna is located 5 Km from the transmitter antenna and the frequency is 900 MHz.
A military satellite uses 10 GHz for the downlink frequency. The distance to the satellite is approximately 36000 km. if the satellite transmitter produces a power of 50 dBm with a transmit antenna gain of 20 dB and on the ground
The frequency response of the circuit is then expressed as a voltage divider involving Zeq and R: 1) Rewrite the equation above in the form: 2)Derive expressions for K, w_n (the corner frequency of an additional zero in the numerator due to the resis..
A plane circular disk of radius 0.25m rotates at a speed of 200 rad/s about an axis through the center of the disk perpendicular to the plane of the disk. There is a uniform magnetic flux B = 1 Tesla parallel to the axis of rotation.
A wattmeter connected to a 240-volt 60 Hz series RL circuitindicates a reading of 691 watts. A clamp-on ammeter used to measure current flow indicates a current of 4.8 A.
A STAIRCASE LIGHT IS CONTROLLED BY TWO SWITCHES, ONE AT THE TOP OF THE STAIRS AND THE ANOTHER AT THE BOTTOM OF THE STAIRS. A)MAKE A TRUTH TABLE FOR THIS SYSTEM
calculate the minimum sampling interval (time period for counting the pulse train) to achieve a speed resolution of 5 rpm, and the number of bits that must be there in the binary counter if the pulse train is to be sampled with this interval for a..
Suppose the RTD of (108.1 Ohms) has a dissipation constant of 25mW/°C and is used in a circuit that puts 8 mA through the sensor. If the RTD (108.1 Ohms) is placed in a bath at 100°C, what resistance will the RTD have
What is the capacitance ratio for the capacitors with Ta2O5 and oxide/nitride/oxide dielectrics for the same thickness, provided the oxide/nitride/oxide has thickness ratio 1:1:1 for the oxide to the nitride
