A particular amplifier has the following low critical frequencies: 25 Hz, 42 Hz, and 136 Hz. It also has high critical frequencies of 8 kHz and 20 kHz. Determine the upper and lower critical frequencies.
Plot a FFT for each signal- For each signal, plot an FFT with amplitude units of mils pk-pk.- What is the sample frequency (fs) for each signal?
The input resistance Ri f is assumed to be small, the output - What is the expression for βg? - If Az = 5 × 106 Ω and Azf = 5 × 104 Ω, what is the required βg and RF?
Cars arrive at a toll plaza at the rate of 60 cars per hour. There are four booths, each capable of servicing 30 car per hour. Assume a Poisson distribution for arrivals and an exponential distribution for service time.
An audio signal s(t) generated by a loudspeaker is reflectedat two different walls with reflection coefficientsr1 and r2. The signal x(t)recorded by a microphone close to the loudspeaker, after sampling,is: x(n) = s(n) + r1s(n-k1) +r2s(n-k2)
Many critics of the Bureau of Reclamation contend that the dam should never have been built, given the highly cracked nature of the rock in the surrounding canyon walls. Should the dam have been built under these circumstances?

Discuss different applications that could use non-inverting and inverting amplifier circuits. Will the actual op amp characteristics cause any challenges if used for each application
In a binary communication system over an additive white Gaussian noise channel, two messages represented by antipodal signals andare transmitted. The probabilities of the two messages arep and 1-p, respectively
A DC series generator is supplying a current of 5A to a series lighting system through a feeder of a total resistance 10 ohms.The terminal voltage is 2500V and the armature series field resistance 18 ohms and 15 ohms respectively.
For each of the following systems with input x(t) and output y(t), state whether or not the system is (i) Linear and (ii) Time Invariant. Note that x(t) could be any complex valued signal. (a) y(t) = a^2 x(t), where a is a complex number.
