For the transfer functionT(s)= (250s (s+300))/((s+10)(s+1000))
Construct the straight line Bode plot of the gain. Is this a low-pass, high-pass, bandpass, or bandstop function? Estimate the cutoff frequency and the passband gain.
Note that s = jw. This problem uses the letter T for system function.
one question: During each cycle, the velocity v (in mm/s) of a piston is v = 6t - 6t^2, where t is the time (in sec). Find the displacement s of the piston after 0.75 sec if the initial displacement is zero.
A 4 pole 50 kW dc machine has a value of Ea = 110 V at 1100 rpm. What is the induced voltage is the speed is increased 20%. Note: omega(w) = (2f*n)/60 where omega is in rad/sec, and n is in rpm
Design a logic circuit with 8-inputs and 4-outputs. The circuit should count the number of 1's in the input. The output should be values between 0 and 8.
A 15-kVA, 8000/230-V distribution transformer has an impedance referred to the primary of 80+j300 ohm. The components of the excitation branch referred to the primary side are Rc= 350k ohm and Xm=70k ohm.
An electric kettle needs six minutes to boil 2 kg of water from the initial temperature of 20"C. The cost of electrical energy required for operation is 12 paise, the rate being 40 paise per kWh.
A signal x(t) is sampled 4 times and the samples are {x[0], x[1], x[2], x[3]}. Its DFT harmonic function is {X[0], X[1], X[2], X[3]}. X[3] can be written as X[3] = a x[0] + b x[1] + c x[2] + d x[3]. What are the values of a,b,c and d
