1) You can adjust the audio level with the volume control. As stated earlier this gives a qualitative measurement of the field strength at that frequency. 2) I realise there...

Well, I was kind of hoping someone would raise an objection to using a radio receiver like this. Determining the total background RF at a particular location using a radio...

radio volume will be the internal control of amplifier right? how does it being maintained constant at various frequencies/power, convey the strength of the signal received?Well, if you adjust the...

Can you think of a way to use a multimeter as a signal meter that measures field strength? If you attach an antenna (aerial) to one of the inputs, and...

Mass is conserved. An electron has, like all massive particles, a rest mass. But electrons can only truly be at rest at absolute zero, and because of the uncertainty principle...

durgais it measuring the received power or frequency?By "it" I assume you mean the radio? The power depends on the strength of the field, so a radio will output sound...

Riddle me this: If you have a battery-powered radio, can you think of a way to use it to get a qualitative measurement of local field strength of RF? I...

I assume you mean a waveform generator? A piece of equipment that has sine, sawtooth, square, etc waveforms at various amplitudes and frequencies that can be injected into another circuit...

You may have heard of the Connection Machine. This was/is a massively parallel system in which the processors communicate with each other via a comms net, which has a hypercube...

Compressing files is about redundant codes. What counts as redundant depends on the file. Check out what MPEG and JPEG compression is about--the discrete Hadamard transform.
