Preface

Over the years, I have published a large number of DSP tutorials on various websites. This collection, which is a work in process, gathers the moresignificant of those tutorials into a common location to make them more readily available for Connexions users.

Some of the tutorials were originally published ten or more years ago. However, you need not be concerned about the material in those tutorialsbecoming obsolete. The concepts and algorithms involved in DSP (such as convolution, correlation, the discrete Fourier transform and the Fast FourierTransform) are essentially the same today as they were when they first became practical for use on digital computers around 1960. (However, the hardware used to implement those algorithms has become much smaller and muchfaster.)

As I have time available, I am converting the tutorials from their original HTML format into the Openstax format that you are accustomed to seeing. You willfind that some of the tutorials are available in Openstax format, and others are available in HTML or PDF format as described below.

Legacy versus openstax presentation format

Early in 2014, cnx.org began a transition from a legacy presentation format to a new openstax presentation format. As of October 8, 2015, some ofthe functionality of the legacy presentation format that is required by modules in this collection have not yet been ported to the openstax presentation format. (In particular, image files referenced by hyperlinks in HTML versions of thetutorials may not display properly in the openstax presentation format.)

This issue should be resolved at some point in the future. In the meantime, one of your options is to select and view the PDF versions of the tutorials using the PDF links that are provided.

A second option is to click the Legacy Site link at the top of this page (assuming that you are not already on the Legacy Site) and view the tutorials in their original HTML format. (The HTML format is more reliable than the PDF format, particularly with regardto source code listings.)

Later, when the issue mentioned above is resolved, you can select either the PDF versions or the HTMLversions directly from the openstax presentation page, whichever you prefer.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

how do lnternal energy measures
Esrael
Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?
Robert

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
