op-amp drawing and function?
108096
Op-amp is short of Operational amplifier.  An op amp is defined as:\n   Vout = (V+ - V-) * Gopenloop\nThe ideal op-amp as infinite open loop gain and is not realizable.  Op-amps were originally designed for performing mathematical operations, hence the name.  Op-amps are still used in many applications including analog computers nad control feedback loops.

More info is needed. \n\nWhat is the pass band frequency, what is the spectral content of the input signal. Ideally how steep do you want it?

a drawbridge or a circuit??

Since it is only 16 options, you can just use a logic circuit. If it were more it would be best to convert each bit to analog with a summing op-amp circuit and have each bit input resistor double the last value. Then the two values could be fed into a comparator. A special logic circuit would need to be added for the equal [same as below] which would then logically override the comparator output for a 1 or 0 meaning L or G. \n[it would do this by making the outputs: \nG = comparator_output and not E  \nL = not comparator_output and not e]\n\nTo make the logic circuit you will need a bunch of logic gates. You can do everything with a slew of two input nor gates, or you can get some ands, ors, xors, and inverters of as many as 4 inputs each. That is up to you. \n\nTo figure out how to hook them up you need to draw a grid that is 4x4, down the side label it with the first number AB possible values:00,01,10,11 across the top label it with the second number CD possible values:00,01,10,11.\n\nNow in the grid fill in what output you want, presumably you will have three outputs, E,L, and G. E would be diagnal from top left to bottom right. The six above and right are Gs, and the six below and left are Ls.\n\nLike this except straight and with lines:\nAB  CD:00,01,10,11\n00      E  G  G  G\n01      L  E  G  G\n10      L  L  E  G\n11      L  L  L  E\n\nnow take each area that you can can and work it into the logic equation. For example the Es are two xor gates ANDed together. \nE = ((a xor c) and (b xor d)) [this is kind of by definition of equals there was no real trick here]\n\nthen you can see the top-right four Gs can easily be singled out with:\nG(1)=(c and (not a))  [that is c is 1 and a is 0]\n\nnow you can do the same for the Ls on the bottom left:\nL(1)=(a and (not c))\n\nNow you can pick up the straglers one at a time or as a group. for example the AB/CD=11/10 is an L, and so is the entire bottom row where ab=11 except for the E which is already known. so you could do this:\n\nL(2)=(a and b and c and (not d)) [to pick it up alone]\nor \nL(2)=(a and b and (not e)) [which gets some other Ls you already got which is fine since you are going to and all the Ls together later to get the final L]\n\nnow you need L(3) and then pick up G(2) and G(3) the same way. After that the final step is to or them all together:\n\nL= L(1) or L(2) or L(3) [same for Gs]\n\nNow you can take the rules for modifying and simplifying the gates down to only 2-input nors if you want, or you can keep all the various gates and hook them all up. \n\nIf you really want to get fancy then you can send the output to an alphanumeric LED and actually print the letter, but that is a whole nother task. \n\nEach segment would then be either always on, always off, or some logical combination of the three outputs G and E [since the L segments would always be on]

Wave shaping circuits are used in function generators.  You might get some help here http://en.wikipedia.org/wiki/Function_generator

i=C(dV/dt)\n\nwhere\n i= the instanious current through the cap\nC= the cap siz in farads\ndV= the change in voltage\ndt= the change in time\n\nI use this equation in my op-amp class where were are doing PWM power supplies and motor drivers right now.

An OP amp is short for Operational Amplifier. This thing can be used for many applications in the electronics field.  Basically, an OP amp is comparable to a single transistor except that an OP amp has 2 inputs. One input can except positive input, and the other input accepts negative signal. OP amps have high input impedance in the order of 1megaohm or more. The output impedance is in the order of roughly around 75 ohms. You can use it as an open or closed loop -- meaning that the output of an OP amp is fed back to either the negative or positive input. One thing about OP amp is that it has infinitely high output gain when operated as open loop, whereas in close loop you can adjust your gain via using a larger resistor on the feedback loop line. The gain is determined by feedback resistor divided by input resistor. Is this too deep for you? Let me back up a little.\n\nAn OP amp can be used as an audio amplier, or RF amplier. \nIt is widely used in practically every application whether it is a car stereo, TV, home stereo, computer, and just about anything that involves electronics nowadays.

If you mean adding a constant voltage to a variable voltage, why not just use a zener diode (with voltage divider as needed)?  If you want the shifted level to appear at the output of an op amp you can put the zener in the feedback loop.  Either way make sure enough current flows through the zener to get the real zener voltage rather than a lower voltage due to zener current leakage.

Here are some sites that may help.  Both have circuit examples utilizing LVDT's.  Hope this helps.

Since you have no contact info, I have no other choice...\n\nIn reference to http://answers.yahoo.com/question/index?qid=20061115060801AAEHWQA&r=w&pa=FZptHWf.BGRX3OFMhzdTUCYEW59bygAIQoCa4DY8zIlrypTkPQ--&paid=answered#NbUvWju8VzmdRHfXRHQU\n\nYou suggested to the asker to wire his sub to 1 ohm when it clearly states in his question "500 watts X 1 @ 4 ohms". You do realize you told him to blow his amp up by wiring it that way.
