How many poles does a second-order low-pass filter have? How many resistors and how many capacitors are used in the frequency-selective circuit?
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.
A linear histogram test was performed on an unsigned binary 4-bit ADC resulting in the following distribution of code hits beginning with code 0
An aluminum cylindrical strain gage load cell is to be specified tomeasure a force of 100,000lbs. The maximum stress in the metal isto be 20,000 psi, the modulus of elasticity is 9.5 x 106psi, and Poisson' ratio is 0.33.
Assume that you are building a three-stage amplifier. When you test it, you discover that it is producing an output signal with no input signal. Explain how this is possible. What are some of the things you can do to eliminate the unwanted signal?
Explain the statement that induction motor is fundamentally a Transformer?
Suppose we discovered that the charge of the electron were not quantized; that is, that the charge of the electron is not fixed. Speculate on the consequences of this "discovery."
n electrical heater is connected to a constant 250-V sourceand absorbs 1000W. Subsequently, the heater is connected to a constant 220-Vsource. What power does it absorb from the 220-V source. What is the resistance of the heate.
Determine the junction capacitance per unit area.
How does the calculation of demand responsiveness in Linesville change if customers rent two videos at a time? What intuition can you draw from this about the magnitude of price competition in various types of markets?
A 10-bit 5-V ADC operates with a sampling frequency of 1 MHz. If a sinusoidal histogram test is to be conducted on this ADC with a test time of no more than 15 ms, estimate the worst-case voltage resolution for this test.
Eble Company proposes to invest $6 million in a new type of text printing equipment. The fixed costs are $1 million per year. The equipment is expected to last for 5 years. The manufacturing costs per hammer is $1. Calculate the break-even volume ..
In class we saw an example of 'Beat note'. In this problem we consider a more general case. Let fc > 0, fd > 0 and define a signal x as.
