^SCs Versus VT devices

^SCs Versus VT devices 

Semiconducting devices are the basic building blocks of all the modern electronic circuits & have following advantages over conventional vacuum tubes:

  1. don’ require a heating battery & thus set in to operation as soon as the circuit is switched on.
  2. require comparatively low voltage for their operation.
  3. don’t produce any humming noise during their operation.
  4. shock proof, small & compact in size, cheaper than vacuum tubes, have a very long life & are free from vacuum deterioration trouble.

Limitations

  1. higher noise level.
  2. can’t handle as much as power as ordinary tubes can.
  3. poor response in high frequency range.
  4. temperature sensitive (maxi. tolerance 50 0C).
