What's the best minor for electrical engineering major? I'm interested in computational mathemetics and computer science.

Yes, I think you are right. The circuit for this graph is a non-inverting amplifier made from a 741 op-amp. Op-amp performance is limited at high frequency; it behaves as a low-pass filter. "In case of a low-pass filter or baseband signal, the bandwidth is equal to its upper cutoff...

Thanks

Thanks everyone, the circuit finally works.

Like this? Output is square wave and amplitude is 6.618V, gain is still not equal to R2/R1.

Ok, a gain is observed now. Output amplitude is 8.032V but a gain equal to R2/R1 is intent, what am I doing wrong?

What am i doing wrong? Still no observed gain.

What's wrong with my circuit simulation? No gain is observed at the amplifier output. The intent is for the output gain of the 741 operational amplifier to be equal to R2/R1.

Oh, so... VD = VDD - I×R Re-arranging gets: I = VDD/R - VD/R Where VDD/R is the I-intercept and -1/R is the slope.

What is the load line equation for I-V Characteristic plots? Why is load line slope negative? According to Ohm's Law: i = V/R; so as voltage increases current increases then slope should be positive, right?

What is typical internal resistance of a voltage meter on a handheld analog multimeter, and also what is typical resistance on its ammeter?

Homework Statement A 4-kg projectile travels with a horizontal velocity of 600 m/s before it explodes and breaks into two fragments A and B of mass 1.5 kg and 2.5 kg, respectively. If the fragments travel along the parabolic trajectories shown, determine the magnitude of velocity of each...

It doesn't agree with my textbook's answer, T = 361 N

Homework Statement The Ball has a mass of 30 kg and a speed v = 4 m/s at the instant it is at its lowest point, θ = 0°. Determine the tension in the cord and the rate at which the ball's speed is decreasing at the instant θ = 20°. Neglect the size of the ball. Homework Equations ΣF...
