What are Op-Amps used for?

The op-amp is basically a differential amplifier having a large voltage gain, very high input impedance and low output impedance. The op-amp has a "inverting" or (-) input and "noninverting" or (+) input and a single output. The op-amp is usually powered by a dual polarity power supply in the range of +/- 5 volts to +/- 15 volts.\n\nOne of the most common applications of this device is the propagation of sound, like a line driver for your stereo. The signal from an external source is very low-powered ... the operational amplifier is used to boost the signal to where it can "drive" the speaker to reproduce the sound.\n\nAnywhere a signal needs to be boosted - and distortion minimized - you can find an op-amp configuration of some sort.

A triac is a switch.  A small control current applied to its gate controls the on/off state.  \n\nIn a colour organ, triacs are used to switch lights on and off.\n\nBy generating the control currents from an audio amplifier the lights can be made to pulse in time with the music.

Semiconductors have different uses:\n1. an N-P junction diode can be used as a rectifier, ie, to convert AC to DC [partly or fully] using the tranmission capabilities of transmission in forward & reverse biased situations\n2. an N-P-N or P-N-P triode can be used for rectification with amplification\n3. Doped semiconductors can also be used to construct logic gates in microelectronic devices.

you got a datasheet for opb 706b and details about the intended application?

Polarized capacitors are useful for single direction systems. The gate only opens one way and the lead is always singular in its transfer of power. Because of this the power is at full when it crosses the board and the Resistance is must be manipulated to make sure the power does not overload the system. As an example, most of the older laser systems worked off a polarized capacitor, when activated the capacitor discharged and all the power drained to a single pole. Thus the laser would fire in one burst until the entire capacitor was discharged. \n\nNon-polarized or dual gated systems are omni directional and therefore omni systemic. Meaning the power flow can be multi directional, however because of the multi directional flow the power is decreased more quickly and dispersed over a wider area. Thus it cannot be as useful due to resistance across the board. However non-polarized capacitors work well within the atmosphere of amplifiers, and other more commercially accepted applications. However remember that all capacitors take time to recharge, and must be fully discharged before they can be recharged. Damage could occur when attempting to ram charge any kind of capacitor.

7400 series logic was associated with bipolar technology \nwhile 4000 with cmos\n\nHowever op-amp741 and 7400 are labeled for different reasons.

The decibel (dB) is a measure of the ratio between two quantities, and is used in a wide variety of measurements in acoustics, physics and electronics. While originally only used for power and intensity ratios, it has come to be used more generally in engineering. The decibel is widely used in measurements of the loudness of sound. It is a "dimensionless unit" like percent. Decibels are useful because they allow even very large or small ratios to be represented with a conveniently small number (similar to scientific notation). This is achieved by using a logarithm.

depends on what you want to do with the sound, but generally they use geometry to create sound friendly environments. (feedback reduction,  good resonance reverb, noise reduction, and others)

LNA designed with a single transistor for RF with a smith chart and power circles, or a general amplifier design with op amps?\nNot having enough data from your question I would suggest you use a low noise op amp, it has the bias taken care of. \nLet me know if thats not the case

through winamp you can.

This is an instrument that can measure voltage, reisitance, and current flow.\n\nVOM= Volt Ohm Meter, but it generally has the functions listed above.  The have digital and analog versions.

Signal to Noise is the ratio of avg Power of signal to avg Power of noise expressed mathematically as:\nSNR(dB)= 10Log(signalPower/noisePower) = 20Log(signal Amplitude/noise Amplitude)\nwhere the Amplitude is the RMS amplitude.\n\nAlso of interest is the Dynamic Range. The dynamic range measures the ratio between noise and the greatest un-distorted signal on a channel.\n\nAnother interesting measurement is the THD - Total Harmonic Distortion. Which is measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental.\n\nAlot people always want to know the power of an amp, I have come to enjoy low power and less distorted music is much more pleasing.

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.

yes you can. For real low freq. you can actually do a DC measurement. Just slow the sweep rate way down and you will see it.

It depends on whether you simply want a boost in voltage value or a boost in signal power. In order to simply boost the voltage you need a transformer but if you want the signal the be boosted in power also you what you need is a simple amplifier circuit.Amplifier chips are available in IC patches
