You can buy them in chip form. I think Analog Devices makes them, up to eight bit. They are easier to use and more accurate than anything ou could build from discrete parts.

The link below describes the basics.  Essentially, when you convert a sound from analog to digital, it has been found that if you sample the sound more than two times as fast as the highest sound a human can hear, the human ear cannot distinguish the digital sound from the original sound.  For telephones, for example, the bandwidth is about 4 KHz, so digital telephony has to sample the sound at least 8000 times per second.  For the best digital reproduction of analog sound that the human ear can hear, which is about 22KHz, we would have to sample at least 44000 times per second, which is why the best quality sound your PC records is 44 KHz.  This is called '2-times-oversampling.'  CDs are usually recorded at much higher rates, and they used to advertise CD players at '4-times-oversampling' and '8-times-' and so forth.  These days, even dirt-cheap CD players sample far faster than a human ear can detect, so you don't hear that anymore.

I do not know a preprogrammed utility to do this, but can point you in the direction that you might need to go.  See the reference below for the math and an on-line converter:

Many CRT's can do that. Take a look at these here:\n\nhttp://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=2000190019+70002970+70000422&Subcategory=19&description=&srchInDesc=&minPrice=&maxPrice=&ATTR1=&ATTR2=&ATTR3=&ATTR4=&ATTR5=&ATTR6=2000190019+70002970&ATTR7=&ATTR8=2000190019+70000422&ATTR9=&ATTR10=

yeah you can use a switch (voltage switch) or if you can use binary logic, need to know how much voltage/current you are dealing with

Try the app from the link below. There are a few converters that will do this for you.\n \nhope that helps\nNigel

You can buy a simple Radio Shack police/fire scanner. Essentially the same thing, but a much lower price.

I would suggest, if you can still find some, seven segment hexadecimal driver IC's.  They will convert discrete logic bits into the necessary outputs for a seven segment display.\n\nThe chip has unfortunately been discontinued and are a little fun to find now.  You can build up a substitute using logic gates or a FPGA (if you have access to those and the related equipment).\n\nThis site might be helpful...
