A stationary transmitter has a center frequency of 2 GHz. Compute the maximum and minimum spectral frequencies received by a mobile traveling at a speed of 100 Km/hr. What is the frequency of the received signal if the mobile is moving in a direction perpendicular to the direction of arrival of the transmitted signal: Justify your response using your knowledge of Doppler shift.
Complex Voltage = 10-j20. try to convert it to polar coordinate with my Ti 89 but I keep getting my answers in arc tan.
Capacity, Data and Transfer Rates, Access Time of Disk Drive, A hard disk drive has 10 disks and 18 surfaces available for recording. Each surface is composed of 200 concentric tracks and the disks rotate at 7200 r.p.m.
The voltage across a resistor is given by Ohm's Law: V=R I. Write a program that asks for resistance R in ohms, and current I in amps for several resistors, then calculates and displays the voltage across each resistor.
What is the modulation used to transmit HDTV signals over the air in US terrestrial broadcasting? What is the transmitted bit rate and the compression method?
What is the minimum donor doping required to convert Silicon into a conductor? What is the minimum acceptor doping required to convert Silicon into a conductor?
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31mV/mm with +/-2cm maximum core displacement.
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
Assume you have a receiver with an overall noise figure of 23 dB and a bandwidth of 1 MHz. Assuming the minimum acceptable SNR at the output of the receiver is 6 dB, estimate the minimum detectable signal level in dBm at the receiver input.
What type of cable is necessary for each connection: straight or crossover? You can assume that S1 and S2 do not have the ability to resolve crossovers (called Auto-MDIX).
