An electric bass amp is advertised as being able to deliver 200 Watts toan 8 Ohm speaker and 300 Watts to an 4 Ohm speaker. If the amp is a voltage source with an internal resistance, what is the value of the internal resistance?
what is the shortest possible line length that would exhibit the desired reactance at its input?
find an s-domain transfer function that has a specified frequency response and answer and discuss the following questions: 1. What determines the "order" of a transfer function 2. Given a transfer function, how is its frequency response calculated
what would be the advantage, if any, of using a general equilibrium analysis to answer this question? Illustrate diagrammatically.
Submit an excel spreadsheet with your characterization results, and a screen shot of you amplifier schematics, and your simulation result running a sin wave (Use a vsin for input).
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
The serial ports on two computers which use binary signaling are connected by a twisted pair cable. The cable has a flat frequency response up to 120KHz, with negligible group delay distortion. That is, the bandwidth of the cable is 120KHz.
A three phase, 25-hp, 440-V, 60-Hz, 1750 rpm, wound-rotor induction motor has the following equivalent circuit parameters:R1=0.20 ohms, X1=1.0 ohms, R2=0.15 ohms, X2=0.8 ohms, Xm=30 ohms The motor is connected to a three phase, 440-V, 60-Hz supply.
A temperature sensor covers a range of 0 to 70 degrees C with an output sensitivity of 2 mV/degree C. The sensor is input to an ADC with voltage range of 0 to 4V. What is the value of the feedback resistor required for an inverting amplifier circu..
An nMOSFET and pMOSFET are fabricated with substrate doping concentration of 6x1017/cm3. The gate oxide thickness is 5 nm. (a) Find Vt of the nMOSFET when n+ poly-Si is used to fabricate the gate electrode.
What do you believe would happen, if you removed the 220 ohm resistor from the circuit and connected the LED directly to the 555 integrated circuit. Are there any appreciable differences between labeled, calculated.
The received power at a receiver antenna is -38 dBm. If the system impedance is 50 Ohms, what is the voltage at the receiver antenna. What is the total average power for a commercial AM transmitter with an unmodulated carrier power of 20 kW and 100%..
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..
