Debugging and Testing of a Vacuum Tube Guitar Amplifier

Debugging and Testing of a Vacuum Tube Guitar Amplifier Ben Wojtowicz Prof. Steve Errede Physics 498 POM May 13th, 2005 . ... Last semester, I finished up the construction of the amp and also did some measurements. However, it still needed some debugging. I also wanted to do some more tests on the amp, which I was not able to do last semester ...

Eigenvalues and Eigenvectors

If all 3eigenvalues are distinct →-−%≠0 Hence, /1"=0, i.e., the eigenvectors are orthogonal (linearly independent), and consequently the matrix !is diagonalizable. Note that a diagonalizable matrix !does not guarantee 3distinct eigenvalues.

Optical Interferometers Interference arises whenever there are two (or more) ways for something to happen, e.g., two slits for the light to get from the source to the screen. I = 4I1cos 2(φ/2), with φ= 2 πδ/λ , and path-length difference δ An interferometer is a …

The Human Ear Hearing, Sound Intensity and Loudness Levels

to sound waves in the perilymph fluid. The bending of the stereocilia stimulates the hair cells, which in turn excite neurons in the auditory nerve. The neuron firing/impulse rate on the auditory nerve depends on both the sound intensity I and the frequency f of the sound – e.g. neurons do not fire on every oscillation cycle of frequency

Quantum Tunneling

current density, the wave function must have a position dependent phase. Otherwise, the phase of Ψ(x,t) will be the same as the phase of ∇~Ψ(x,t) and therefore Ψ∗∇~Ψ will be real. The current density for an electron in a stationary state of the form Ψ(x,t)=ψ(x) exp(−iωt) is zero since the phase dependence has no spatial dependence.

Lesson Plan: Electricity and Magnetism

Electricity and magnetism are fundamentally related. 2. Just as electric charge produced an electric field, electric current produces a magnetic field. 3. Since whenever there is current there is charge, both electric and magnetic fields exist.
