the signal shown below is a sine wave as it might be displayed on an oscilloscope. If it takes 40 msec. for the waveform to travel between the points shown by the arrow "B" below, what is the frequency of the waveform?
An automobile manufacturer is concerned about a fault in thebraking mechanism of a particular model. The fault can, onrare occasions, cause a catastrophe at high speed. The distrubution of the number of cars per year that will experience
a lowpass butterworth filter has a corner frequency of 1 khz and a roll-off of 24 db per octave in the stopband. If the output amplitude of a 3 khz sine wave is .1 V, what will be the output amplitude of a 20 khz sine wave if the input amplitudes ..
what are the different methods used in frequency response analysis
You have an amplifer with a nominal open-loop gain of 1000 (A = 1000), but the variance in the gain is 20% (meaning that the open-loop gain ranges in value from 800 to 1200). You want to use feedback to try to desensitize the gain.
A sampled-data system such as that presented in problem (i) has a sampling period T = 0.05s and has G(z) = K (z3 + 10.3614z2 + 9.758z + 0.8353) / (z4 - 3.7123z3 + 5.1644z2 - 3.195z + 0.7408) 1. Determine K when the two real poles break away from the ..
The signal to noise ratio at the receiver is required to be at least 17 dB. The average noise power at the receiver is 1 mW. The cable loss between the transmitter and the receiver is 2.5 dB/km
Store the arrival times in memory locations starting from $1000.(Do this is in C. Store the results in an array and don't worry about the speci c location of the results.)
what is the difference between the words "rated as 3mA" , and "biased at 5mA" , when talking about a diode what is teh difference between saying " the diode is rated as a 3mA device", and " The diode is biased at a current of 0.5mA"
Design a circuit to capture the pressing of buttons (momentary switches). The circuit should have two LEDs "A" and "B", and two buttons, "A" and "B". Whichever button was last pressed should determine which of the two LEDs is lit.
The power dissipated in the resistor is 80 W when connected to a 10V source. Find the total dissipated power when the same resistor is connected to a 5V source.
Consider a 6 cm2 dye sensitised solar cell with reverse saturation current Jr=10-10A/cm2. When the solar irradiance is 1,000 W/m2, it produces an equivalent photo current/short circuit current of 15 mA/cm2 at 300 K.
A random variable X has a variance of 9 and a statistically independent random variable Y has a variance of 25. Their sum is another random variable Z=X+Y. Without assuming that either random variable has a zero mean
