(a) Draw the equivalent circuit. (b) Determine the ohmic value of the impedances. (c) Calculate the source current in amperes and in percent if the generator operating voltage is 3.8 kV (line-to-line) and a reactance of X=125% is connected in seri..
A given cable has characteristic impedance Z0 = 100 Ohms. At a given position on the line, the voltage amplitude is 1 V. Draw a sketch (a snapshot at a fixed time) of the forward-traveling voltage and current waves on the line, showing their amplit..
An isolated free electron is traveling through an electric field from some initial point where its coulombic potential energy per unit charge (voltage) is 17 kJ/C and velocity = 93 Mm/s to some final point where its coulombic potential per unit ch..
What RF bandwidth must the radio link provide if the modulation is binary phase shift keying (BPSK)?
The charge entering the positive terminal of an element is q = 10 sin 4 piet mC while the voltage across the element (plus to minus) is v = 2 cos 4 pie t V. (a) Find the power delivered to the element at t = 0.3 s.
The 741 op amp is usually modeled on specification sheets as a voltage amplifier having the following parameters: Rin = 1 M, Av = 100,000, and Rout = 100 Using this information, develop equivalent circuits for the 741 as a current amplifier
Determine the voltage required on the input of the amplifier to give the maximum output of 85 dBuV. If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBuV, calculate the signal-to-noise ratio on the output of the amplifi..
write a script that will call: a function to prompt the user for an angle in degrees and call a function to calculate and return the angle in radians (note:pi radian =180) and call a function to print the result.
