A digital storage oscilloscope is specified to have a sample rate of 400 MS/s and an acquisition memory of 20K.
(a) Determine the slowest possible time-base setting for which the specified sample rate is achievable.
(b) If the time-base setting were 1 ms per division, what sampling rate would be achievable in this case?
Assuming a third-order nonlinearity for the envelope detector in Figure, prove that the output spectrum of the system exhibits growth in the adjacent channels.
A certain amplifier has an open-loop gain in the midrange of 180000 and an open loop critical frequency of 15000 Hz. If the attenuation of the feedback gain is .015, what is the closed-loop bandwidth. solve?
Each hydroelectric unit at the Grand Coulee Dam takes in water at a rate of 8.50 X 105 kg/s from a height of 87.0 m. The power developed by the falling water is converted to electric power with an efficiency of 85.0%. How much electric power is pr..
A designer searches for a simple circuit to provide one-third of a signal current I to a load resistance R. Suggest a solution using one resistor. What must its value be. What is the input resistance of the resulting current divider
In the absence of any special knowledge of network conditions, the typical approach is to pick an arbitrary value, such as 3 s, and hope that this will converge quickly to an accurate value. If this estimate is too small, TCP will perform unnecess..
assuming a unilateral device. Use these results to find the equivalent circuit parameters for the HEMT device whose scattering parameters are given in Table 11.7, at a frequency of 2.0 GHz. Ignore S12.
The unit impulse response of an LTIC systems is h(t)=2e^-4t u(t). Find and sketch this system's (zero-state) response y(t) if the input f(t) is e^-6t u(t).
Suppose that one wishes to use reverse osmosis to reduce the salt content of brackish water containing 0.22 Mtotal salt concentration to a value of 0.01 M, thus rendering it usable for human consumption. What is the minimum pressure that needs to ..
Calculate the resonant and antiresonant natural frequency and relevant damping factors.
Calculate this transformer's voltage regulation under the same conditions, using the per-unit system.
What are the possible speeds at which the rotor can supply power to this load at 25 Hz? What would be the ratio of voltages at load terminals at these speeds? Assume the stator and rotor impedances to be negligible.
Repeat the computer experiment of Section 10.21, this time using the recursive leastsquares (RLS) algorithm in place of the LMS algorithm.
