[Ideas for a New Project]

It will be very nice if you could think of some Networking projects such as "Practical Validation of various MAC layer protocols" or something of that sort.

[Led display Digital Voltmeter question]

Some people recommend using IC for generating the -5V. But the best thing to do is to have a resistor divider across the -15 V which is available in all the voltage source to produce the -5V.

[idea of infinite energy]

We all know that a noise have an flat spectrum. Also we know that the noise have an inverse fourier transform approximately equal to a dirac function. The energy of this signal is very high (going to infinity almost). Can we tap a very high amount of energy from this signal at that instant. Please send in your criticism about this idea and feasibility that it will work.

[low pass filter]

Anyone got an idea of how a filter can have a roll off rate greater than 20 db per decade using a single pole or more than 40 db per decade using a double pole.
