PurpleBadger 0 #1 June 25, 2003 Electronics exam in 3hrs 6 mins... and I've just spent the whole night post whoring (whilst glancing over notes ) ... if anybody has any worldly tips on things that might help me pass then they would be most appriciated!!!

freakshow 0 #3 June 25, 2003 1) smoke is bad 2) water and electronics usually don't mix (see #1) that's about all the help I can give right now B.L. (the brain) Quote Share this post Link to post Share on other sites
Zeemax 0 #4 June 25, 2003 yes, logic gates are comlicated. Logic clocks are worse.

You have failed Quote Share this post Link to post Share on other sites billvon 3,100 #11 June 25, 2003 Let's see. Terminate high speed single ended clock lines with an RC termination. Use flyback diodes when driving relays with solid state logic to prevent inductive kick. Don't neglect parasitic capacitance when designing high frequency magnetic for switching power supplies. It's a lot more efficient to drive LED's in one long string with a current regulated boost supply than use a whole lot of dropping resistors, especially at low voltage. Beware the coup de fouet when trying to gas-gauge lead acid batteries. MOSFETs are easier to drive than bipolars. How's that?
