      Welcome to the group, Kirk.

      This type of stuff shows up on eBay quite frequently. Of course, you could
      sell it off to a surplus dealer, but will take quite a hit for the
      convenience. A third option is to create you own web site and sell it off
      directly, person-to-person. With Pay-pal and a little web knowledge, it
      would be simple to make a little commerce site until it was all gone.

      ...then again, you could send it all to me, as it is probably all worthless,
      anyway. I'll even pay the shipping ;)

      Hi, i just joined your group and will no doubt post when i have
      something to contribute.

      Meanwhile I'm the trustee of an estate that possesses a really large
      quantity of electronic parts that i have been "appointed" to sell off.

      Mostly lots of 2 amp 24 vac power transformers, Really fancy 18" wide,
      16" deep, 8" inch tall Optima enclosures; transistors, capacitors,
      resistors, diodes, leds, light bars, optocouplers, power cords, card
      edge connectors; and a really long list of other components.

      So, if anyone has any ideas as to how i should go about selling them,
      please advise.

      Anyway, thats not why I joined, Its just the situation I find myself in !!

        Please could anyone solve this digital communication problem i have tried for several hours but to no avail.

                           question :

        1. A television signal is to use 625line picture  pulse    coded modulated onto a 500Mhz carrier.16 quantisation    levels are considered suffient for the quality of the    picture required (including black and white)
                   
                        Determine the
         i. minimum sampling rate for the baseband signal.
        ii. number of bits/second required for the digital           signal.
        iii.Baud rate of the digital signal.


        2.The digital signal is to be modulated onto a carrier   as a bipolar signal (i.e '1' as a positive pulse; '0'   negative pulse) with a mark/space ratioof 1:1.
          AS an example

                       0110 =

                                ___      ___
                               |    |    |    |
                          ___|    |___|      |___
                   |    |                              |     |
                   |___|                              |___|
