The capacity of a capacitor is measured in farads (F). Ususally they range from several picofarads (pF) to several microfarads (µF). For the measurement, look on the capacitor itself or if it is a disk capacitor then there is a system for figuring that out (look it up).

vertical oscillator/driver shot. shorted capacitor, or maybe transistor/ic? \nnowadays, you might as well trash it if you can get a halfway decent deal on a flat panel. or give it to your cousin who's MIT material to see if he can fix it.

plug off the printer from the electric source... not just close it from the button... and wait 30secs

flip both at same time mark the 4 min time on the 7 min clock(what it looks like with 3 mins left) when the  7 min one is done flip and the 4 min is done and you have the 3min line marked flip only the 7 min clock when it hits that 3 min mark flip the 4min clock exactly at that time when the 3mins has run out there wiil be exactly 1 min in the 4min clock. mark that one min left. then all you have to do is flip the 4min clock three times and you will have your nine minutes

A flip flop is a circuit that can "flip" to one state and then later "flop" to another. So when a flip flop is "set" it has an output of 1 and "reset" it has an output of 0. Unlike other kinds of logic gates, the flip flop "remembers" its state (not after the power goes out though).\n\nSo there are lots of ways to make these. Common practice is to use two NOR gates or two NAND gates cross coupled. However, there are other kinds of flip flops that require more kinds of gates. You can also get ICs that have a flip flop function already built in and that's the easy way.\n\nSee the link below for a light-hearted discussion

Homework, huh?  Badly copied from the source.  Make it an answerable question, clean up the gibberish and try again.  For instance, 90 degrees phase lag at what frequency?  Sorry to be curmudgeonly, but this shouldn't be just about getting answers without understanding.  Anyway, here's a hint.  At 90 degrees, Xr=Xc, and RC=1/(2*pi*f).  For phase lag the R is in series and the C in shunt.

I'm assuming you mean in the context of digital hardware.\n\nYou should browse the electrical engineering/computer engineering programs at various university pages. Some have their lectures posted online, such as this one:\n\nhttp://wearcam.org/ece385/lectureflipflops/flipflops/\n\nMIT also has open courseware (highly recommended).\n\nhttp://ocw.mit.edu/OcwWeb/Electrical-Engineering-and-Computer-Science/index.htm

just add a rewire device from fruity loops. then it should launch reason

Go into your CMOS and check its settings, just because it is capable of going 133 MHz, does not mean it is set to go that fast.  If you cannot up the speed in your CMOS, if it is not set correctly, you will have to get a manual so you can adjust the jumpers.\n\nThis also could be being cause by how you are installing it, you might want to purchase or borrow an external drive and use that for the installation.\n\nJohn B.

The main delay in switching is caused by the switch waiting for the entire packet before sending it out. This is called "Store and Forward". This can be alleviated by setting the switch to use "Cut-Through" switching. Cut-Through may go by other names, such as Fast Forwarding. Usually this is only available on higher end (enterprise class) switches. Switching delay will only ever be a problem if you have MANY switches cascaded together. In a typical environment it is really quite negligable.\n\nWhere you will typically see delay in when dealing with a WAN. There are several types of delay there. \n\n1. Serialization Delay: This delay is inversely proportional to the link speed. It is the amount of time it takes to place the bits on the trasmission medium. On a 10 kbit link it takes 0.1 sec to place 1k of data on the link. on 1 10 Mbit link, it would tak 0.0001 sec to place the same 1k\n\n2. Propegation Delay: This delay is caused by the fact that nothing happens instantaniously. In any transmission medium it takes time to go from point A to point B. For copper (and fiber) the speed is 2/3 C (speed of light). For wireless or satellite the speed is C. \n\n3. Queing Delay: This delay is caused by how long it takes for the router to process the incoming data packet against its various rules and whatnot. Unlike the previous two delays, this one is totally controlable.\n\nI am certain there is one more, but my book is at work.\n\nA good resource for delay is Cisco's QoS book. QoS, by definition, is the management of delay.

You should use pulse width modulation (PWM).  PWM is essentially an on-off sequence in time, like a square wave alternating between 0 and 1.\n\nClearly full voltage will give you maximum speed.  This happens when the voltage is always on.  Now, suppose you only wanted to go half the maximum speed.  You could send a a square wave with 50% duty cycle (on half the time and off half the time) at high enough frequency that the motor will spin at a constant 50% maximum speed.  The motor is like a lowpass filter and therefore, a square wave at high enough frequency will produce a steady response without oscillation.\n\nIf you want the motor to go slower, say, at 25% maximum velocity then send a pulse that is on 25% of the time and off 75% of the time.\n\nIn reality, if you want 25% speed you may have to send something like a 27% duty cycle because of the time delay between commanding 'on' and the system actually turning 'on'.  In this application, though, I don't think you will have this porblem.

That's a tall order.  If I had a spare 18 hrs I'd love to, however...\n\nThere's a chip that does it.  Its called an Arithmetic Logic Unit (ALU).  Here's some suggestions:\nhttp://www.xs4all.nl/~ganswijk/chipdir/f/alu.htm\n\nNo offense, but its a ton of work, with no assurance I'll get my 10 points.
