A perfect conductor 2m long is moved at a speed of 36 Km/hr through a magnetic field having a flux density of 1.0 T. If a 1? resistor is connected across the ends of the conductor, calculate: (a) The induced voltage (b) The current in the circuit (c) The force required to move the conductor through the field (d) The electric power generated
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
An OFDM system with a passband bandwidth of 10 MHz and carrier frequency of 1 GHz is used in an outdoor environment with a maximum delay spread of 15 microseconds.
A filter has the following characteristics: Attenuation is 0 dB from 0 Hz to 2.5 kHz. Phase angle decreases linearly with increasing frequency above 2.5 kHz. Above 5 kHz the filter has steadily increasing attenuation.
An electron is bound in a one-dimensional infinite potential well with a width of 5Å. (a) Calculate the first three energy levels that the electron may occupy. (b) If the electron drops from the third to the second energy level
Consider a direct sequence spread spectrum (DSSS) system attempting to transfer data. The DSSS system has a data rate of 2 Kbps (2 thousand bits/sec) which is spread to 2 Mcps
Suppose that the number of customers entering a department store in a day is a random variable with mean of 50 customers/day. Suppose that the amounts of money spent by each one of these customers are statistically independent.
A 6-bit DAC has an input 1001012 and uses a 10.0-V reference.
The design of a home security system requires the use of sensors, including a sensor to measure carbon dioxide levels. Your search resulted in one sensor that provides an output range of [-2V, 1V].
Discuss the steps required in calculating the collector-emitter voltage in a VDB circuit. Why does this circuit have a very stable Q point Discuss whether transistors being used as switching circuits should be biased in the active region.
What is the motor efficiency as operated?
Include worked solution, a discussion of any differences in the theoretical and measured values and screenshots that show your measurements and paste them into a document
Two resistors are given: R1 = 470 ohms and R2 = 1.20 k ohms. (a) The two resistors are connected in series with a 48 V source. Calculate the series equivalent resistance. Sketch the schematic diagram of the circuit with the two resistors.
