1. For the lowpass RC filter, calculate the phase and magnitude ofthe transfer function at frequencies of 20, 50, 100, 200, 500,1000, and 1500 Hz. Tabulate the result and then sketch themagnitude and the phase of the response as function of thefrequency (use log scale for frequency). Use R=50 kΩ, C=0.02μF
2. Determine the half power frequency fc defined as the frequencyat which the magnitude of the transfer function is at 1/√2 ofits maximum value. Assuming C is fixed at 0.02 μF, calculatethe half power frequencies corresponding to R=20 kΩ, 50kΩ, and 100 kΩ.
If the amplifier is fed from a voltage source Vsig having a resistance Rsig = 1kΩ, find the transfer funtion Vo/Vsig as a function of the complex-frequency variable s and hence the 3-dB frequency fH and the unity-gain frequency ft.
What is the primary source of distortion with a Class B amplifier. What are some ways the distortion can be minimized and discuss the tradeoffs that exist when implementing these distortion minimizing methods.
3-singlephase 2 winding transformers, each rated 500 MVA, 13.8/199.2 kV, with leakage reactance Xeq = 0.10 per unit, are connected to form a three-phase bank. Winding resistances and exciting current are neglected.
To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided
plane polarized light is sent through two consecutive polarizers, the first having its plane of polarization in the same direction as the incident light and the second having its palne at 90 degrees to the original plane of polarization.
Given the following: i) The column vectors: X1=[2 4 6]'; X2=[4 5 7]'; X3=[7 8 3]' % Note the above are column vectors (% In Matlab, ' means Transpose). ii) The matrix: A=[X1 X2 X3]. 1)B=A'; % In Matlab, ' means Transpose. This defines B.
A zippy little electric car is equipped with a 175hp motor. a) How many kW are required to run the motor if we assume ioo percent efficiency in converting electrical power to mechanical power
A special external data signal (DATA_READY) is asserted whenever each of the bits for X are available. In addition, another special signal (ENCODE) is asserted during the transmission of the data X indicating whether 2X+3 or 3X+1 should be compute..
