hi all. stuggling to determine the difference between ISDN and public switched telephone networks (PSTN). I know what each one is individually i just don't know how they relate to each other... Does ISDN use PSTN? What i undersatnd is that PSTNs have only transmitted voice in the past but...

any atmel experts out there?? just need to ask how to write data to an external EEPROM. was wondering if anyone is familair with the atmel chip...

start with wikipedia...

Hi guys, need to purchase some resisters and caps that can tolerate temperatures upto 125 deg. cel. any ideas where i can find some - or what type i should be looking for?? thanks!

just need some help with how to connect external EEPROM to an ATMEL chip...

"If it oscilates at all it's defective or not proper for the rest of the suspension." NoTime>> i couldn't disagree with you more. Whilst the car is in motion - the piston is going to move up and down! Hence the oscillations. It will oscillate! The quality of the shock absorber just determines...

pixel01>> do we assume : B-A1-A2 is the same as A2-A1-B?

Hello everyone! This might be bit of the 'electrical engineering' topic - but maybe someone out there can help :) Does anybody have any idea of what the maximum frequency of a piston in a shock absorber of a forumula 1 car is? What do i mean: How many times does the piston (in a shock...

ok?? what is a SSB receiver?? is it easy to build? ill google it - then talk tomorro thanks

ok - so I am using a linear variable diff transformer to measure vibrations. Such a device takes in an excitation voltage at specified frequency, let's say 10kHz. Now let's say the core is moving with a frequencey of 100Hz - my ouput will now be a modulated signal that will have frequnceies of...

hello all, really stugglin with this one - need to build/design a phase sensitive demodulator - i.e a circuit that can recover my orginal signal... don't suppose anyone has any idea how to go about this or some circuit diagram i could work with? thanks John

hi guys need some component that will take in 12 VDC and put out a negative 5V AND a positive 5V - just a very simple component - a part number would be great - thanks

hello all! Does anybody have any idea how i get get a transfer function for a Linear Variable Differential Transfromer (LVDT). I thought about generating a differential equation to model the LVDT and then taking the laplace transform of this. My problem is: I am really stuggling to model...

Berkemen >> Thanks a lot! I owe you! will take a look at that site! appreciate it! thanks Averagesupernova John

fun? not really :) - don't get to build it! just have to do a hardcore report on it! - must include a final circuit design (with filters, ADC,DAC, amps etc) Can i ask why you so against an LVDT? really don't think anything to with resisatnce is good option in this type of app. Another thing...
