For the circuit in Figure, do the following:
(a) Find the phasor Thévenin equivalent of the source circuit to the left of the interface by hand. Then use Multisim to validate your Thévenin circuit.
(b) Use the equivalent circuit to find the phasor voltage V and current I delivered to the load by hand calculations. Then use Multisim to validate your voltage and current results.
Assume that a transmitter on Earth must communicate with a spacecraft on the Moon. Parameters are: Earth-based atenna gain=40dB Lunar receiving atenna gain=20dB Distance=386,000 Km Frequency= 3GHz Minimum lunar signal level = 100fW
A student from electromechanical systems class planned to construct a transformer that will cause an actual load resistance of 98.5 ohms to appear as 172.8 ohms to an AC voltage source of 176 V rms.
The LF351 is an op amp with a voltage gain of 316,000, a cutoff frequency of 40 Hz, and a roll-off rate of 20 dB per decade. Draw the ideal Bode plot.
A diode is connected in series with a 30-V rms source to charge a 12-V battery with an internal resistance of 0.1 ohm. Specify the series resistance necessary to limit the peak current to 2A. Estimate the time required to recharge a 10-A hr batter..
