    Producing Waveform from Frequency Table

    I'm working on a voice synthesizer. I have my computer set up to accept an 8-bit 44kHz waveform. I'm feeding it sines, adding sines together, and so on. It works great. However, I want to generate a sound given a frequency histogram. That is, I want to generate noise that has a specific...

    Force of the average car crash

    I like to look at this in terms of impulse, i.e., change in momentum. If you know the mass (m) and the speed (v) of the car initially, and we assume that the car comes to a stop after the crash, the total impulse delivered to the car is m*v. If you want to know the average force applied to...

    Intuition for information theory

    What is meant here is that no more than 6-bits PER SYMBOL can be contained in an English message, not 6-bits total. (What I find more interesting is the amount of entropy in an English message; that is, how there is really a lot less than 6-bits of info carried by each symbol in a message ON...

    Simulating Dry Friction: Solving Complex Problems in Driving Simulation"

    This rather simple physics problem is at the heart of any simulation involving rubbing parts. I’m working on a realistic driving simulation which requires accurate friction calculations. The clutch, transmission syncros, and wheels must be simulated as frictional systems. Of course the clutch...

    Structure and Interpretation of Classical Mechanics

    This is an unusual book which uses the Scheme programming language to functionally describe the various components of classical mechanics. I would say it is at the level of a graduate mechanics course (think Goldstein), however students with a strong programming background will find it easier...

    Calculators Online app to replace Online TI-83?

    no ROM Afro_Akuma, i hope you have a friend with another TI-83 so you can rip the rom from it! I am in the same situation, but I need a rom image for the calculator! Looks like I will be searching for a spare TI83 to barrow!
