General background information

What is an AudioGraph ?

A previous module titled Jbs2040-An Audio Graph of a Sinusoid introduced you to the concept of an AudioGraph . In a nutshell, an AudioGraph is a melody consisting of audio pulses that represent points on thegraph of a function. Those points represent values of y as a function of x between two limits on x.

Two different AudioGraph programs were presented in earlier modules. Each was specifically designed for a particular function. One program produced anAudioGraph of a square wave. The other produced an AudioGraph of a sinusoid.

A general purpose AudioGraph program

This module expands on that concept and develops a general purpose program named MusicComposer10 that can produce an AudioGraph for virtually any single-valued function of the independent variable x for which the values of y can be encapsulated ina simple text file. Several examples are provided above . (By single-valued function in this context, I mean a function where, for every value of x within the range ofinterest, one and only one finite value exists for y.)

Where do the text files come from ?

The program doesn't know and doesn't care where the values in the text file originate. For example, they could represent the temperature in your dorm room takenmanually every hour for 36 hours and entered into a text file using a simple text editor program. On the other hand, they could be produced by acomputer program that is designed to evaluate a specific function and to write the results into an output text file as was the case for Sinc01 .

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
