A transistor amplifier has a midband gain of -120, a high cutoff frequency of 36 kHz, and a bandwidth of 35.8 kHz. In addition,the actual response is also about -15 dB at f=50 Hz. Write the transfer function for the amplifier.
A 3 phase, 208V, 4 pole, 60Hz, Y connected synchronous generator has a synchronous reactance of 8 ohm. Assume the resistance of this generator is negligible. The machine terminal voltage is maintained constant at 208V (line to line).
Using DC Operating point analysis in Multisim (DO NOT USE MULTIMETER INSTRUMENT-NO CREDIT) determine the emitter voltage and emitter current. Provide a screenshot of the results window.
A coaxial cable contains material with a dielectric constant of 9. The diameter of the inner conductor is 2 mm and the diameter of the outer conductor is 12 mm. Determine the characteristic impedance in ohms
A particular intrinsic semiconductor has a resistivity of 50 -cm at T=300 K and 5 - cm at T=330 K. Neglecting the change in mobility and effective density of states with temperature, determine the bandgap energy of the semiconductor.
Compare the Bandwidths of Two Inverting Amplifiers a) Use Signal Express to measure the 3 dB bandwidth for the inverting amplifier with a gain of -10 and for an inverting amplifier with a gain of -50. b) How does the bandwidth change with gain

This assignment contains electronics engineering questions like State the commonly found components of a SCADA (Supervisory control and data acquisition) system. and decribe the function of the HMI in a SCADA system.
e) What is the value of C such that the energy stored in the capacitor equals the energy stored in the inductor f) How much energy is stored in the 3.9?F capacitor Use the formula for the energy. g) What is the power dissipated in the resistors
Determine which of these properties hold or don't hold for the following discrete time systems. Justify your answers. IN each example, y(t) denotes the system output and x(t) denotes the system input.
A Si pn junction diode is described by its I-V equation, I?= Is exp (V?/V?) ,where V?=25mV, Is=10-14A . It is desired to derive constant drop and PWL models for the diode assuming an operating current between 1mA and 3mA.
