If i apply a 100hz and 200hz signal to a speaker, will the spaker vibrate at 150hz?

you would hear the resultant of the two frequencies both in frequencie and amplitude.

To answer the question properly, need to know more about the nature of the signal.\n\nWhat is the signal bandwidth (what is the fastest that the signal is changing?)\n\nWhat is the dynamic range of the signal? (What is the ratio of the are the maximum-to-minimum values expected)\n\nWhat amount (%) of error can you tolerate in each measurement?\n\nFlash conversion is very fast, but is power hungry and limited in its number of bits. I'd probably choose this one only if there were no other alternatives. Considering that seismic events are relatively slow with respect to the typical speeds of electronics, I might expect that a flash converter may not be necessary.\n\nThere are several very fast successive-approximation ADCs that could probably do the job. And they are cheap!\n\nSigma-delta converters are relatively slow, but have a very wide dynamic range. Useful for high precision across a wide range.\n\nCheck out www.analog.com. They make a lot of converters, you can probably find some application notes on the topic.

depends how much the volume is off by

there will stretching to the string, and the amplitude and frequency will be tranmitted....but the cycles wont be at light speed...so they wont allow for instantaneous communication.  Now if the cable was fiberoptic...and pulses were transmitted...hmm

See the answer to your other question about the bb repeater.  I hope it helps.

Well, you could build a *relatively* simple circuit that simply cut the frequency in half, but then again, what kind of sensor are you dealing with?\n\nWhy do you want to tune it to a lower frequency? It is not simple to just shift a frequency, there are many things to take into account; input impedance, output impedance (both may be frequency dependent), signal amplitude, and required voltage swing.\nI would only attempt this if it was not a vital sensor I was messing with.

As frequency increases the wavelength decreases and the equipment needed to transmit a certain distance doesn't need to be as strong. This allows the same powered transmitter to transmit a longer distance. This is why radio frequencies can travel a long distance but the output of a loudspeaker cannot.\n\nI think that was the answer you were looking for, since attenuation would be device dependant.

Look at the power plug for your speakers, it should have the power rating on it.

use of a vibr-ator against a clit?

You might want to try and use Sensodyne.

Check to see if your raido is plugged into the same receptacle as, say, a computer, or TV - the noise is most likely a 60Hz humm caused by a common ground with these types of equipment.  Also, shielded cable between the radio and the speaker would be helpful.

well it wouldn't BE the computer that generates it, but rather a device attached that would emit those frequencies.\n\nspeakers won't....no point in designing sound range capability that is, by definition in-audiable.\n\nthough I guess if you were to modify a hard drive you could creat freqs in that range....though how to confirm it....?

Go to this site http://www.bksv.com/pdf/Measuring_Vibration.pdf it should help you out with your question.

Not necessarily! \n\nOutput is usually measured in watts at the speaker connections, not volts.\n\nThe Line-out "standard" is 1v peak-to-peak on most systems except those designed to drive many speakers, (like restaurant background music), which are usually either 75v or 150v to avoid "line loss" in large systems with long runs, which then use special transformers at each speaker to convert back for the speakers.

you can use a fm modulator

Let f1 = 35.0 kHz\nvbat = 12 m/s\nvsound = 330 m/s\n\na) f2  = vsound*f1/(vsound-vbat) = 330*35/(330-12) = 36.32kHz\n\nb) For bat f = (vsound+vbat)*f2/vsound = 342*36.32/330 = 37.64kHz\n\nc) It will obviously affect the answers
