My Light Diagram

The OP AMP Integrator , is a circuit which performs the integration of an input signal. The output of an integrator will be the mathematical integral value of continuous input signal. Such a circuit is obtained by using a basic inverting amplifier configuration if the feedback resistor Rf is replaced by a capacitor Cf. V o = -1/R 1 C F  ∫ 0 T (Vin dt + C) The above equation shows that the output voltage is directly proportional to the negative integral of input voltage and inversely proportional to the time constant R1Cf.

Not expensive, High-quality sound, Small parts and easy to assemble, Do not need to be tuned.Today can offer to your attention an amplifier that I have gathered from (almost) stuff I have lying in store. Long ago, working in the workshop, we often filmed amplifiers machines, since they come without tape recorders ​​and to put an ordinary tape recorder had to dismantle the amplifiers are !!! I left a couple of times since amplifier chips such as the LA4708. Time has passed since then a lot until my sister had not asked to do anything for his laptop to play in the yard with an acceptable quality and loud sound as speakers 2 pcs idle at home! Power 2h-30-Vatt 12 volts, working scheme It is taken from the datasheet half and half just from the people and schemes are proven over the years !!! If you look at the diagram, the capacitors C3 and C4 - a savings standing on the output of the amplifier, without a way (as if the sound disappears at high bass and not enough to drive the speakers). Th...
