Amplifier with input resistance of 100k Ohm, an open circuit voltage gain of 100 V/V and output resistance of 100k Ohm is connected between a 10k Ohm signal source and 1k Ohm load. Find the overall voltage gain Gv and also find the current gain
A perfect inductor with L = 0.2 H is connected in series to a voltage source with: v(t) = 10cos(40pi(t) 20degrees). What is the reactance of the inductor
What is the resistivity of the wire? conductivity? Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
a series parallel circuit with a 3V dc power source connected to 3 resistors. R1 and R2 are in series with the voltage source and R3 is in parallel with R2. It is given that 4amps is flowing through R1 and 2amps is flowing through R2.
The Signal power to noise power ratio is an important measure of the transmission quality of any channel. If at the receiver there is a 12 dB signal to noise ratio and the received signal power is 50 micro W then calculate the received noise power..
Shirlee is working with a measurement tool that reports measurements in centimeters. Since Shirlee is unfamiliar with centimeters, she would like her centimeter measurements to be converted into yards, feet, and inches.
The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a non-inverting configuration with dual supplies (+5v and -5v)..
The current is due to free electrons moving through the wire at an average velocity of v meters/second. If the concentration of free electrons is 10^29 electrons per cubic meter and if they are uniformly dispersed throughout the wire, then what is..
A random variable X has a variance of 9 and a statistically independent random variable Y has a variance of 25. Their sum is another random variable Z=X+Y. Without assuming that either random variable has a zero mean
1. Compute the probability of having the sum of 10 by throwing (a) two dice, (b) three dice. 2. What is the probability of three of a kind for a poker hand with (a) a card deck of 52 cards, (b) a card deck of 32 cards
Assume you have a receiver with an overall noise figure of 23 dB and a bandwidth of 1 MHz. Assuming the minimum acceptable SNR at the output of the receiver is 6 dB, estimate the minimum detectable signal level in dBm at the receiver input.
In a circuit, a resistor is only element that has resistance. The generator voltage varies in time, where the amplitude of e max= 1.2 volt and emf freq.= 0.5 Hz , which the max current is equal to the max current when the freq. of emf = 3.0 Hz,
n a symmetrical T attenuator pad, each series arm has a resistance of 35-ohm and the shunt arm has a resistance of 110. Determine a. the characteristic impedance b. the insertion loss when feeding a matched load c. the A B C D constants of t..
