  Small signal analysis not only limited to low power but also the Frequency of operation below the Lower cut off frequency
  
  Large signal analysis is for studying operation above the upper cut off frequency

  Thanks for your reply "Conquerer", but still
  -Are you implying that small signal analysis is meant for dc frequencies?
  -And aren't the cutoff frequencies dependent on circuit elements?

  Yeah true Small signal analysis is not on DC frequencies alone It extends to nearly audio range
  
  Yeah the cut off frequencies are determined by the Capacitors and inductors in the circuit

  Some of my doubt still remains, I guess I've got to solve questions
  
  Well anyway, thanks for your reply

  Post your question friend lets see what we can do
  
  Every transistor has its own operating frequency range
  
  Refer the data sheet that will be effectively explain your frequency range issues
