HP48/49 - BODE v2.31sg


  • Detailed analysis of all zeros and poles of the given transfer function.
  • Construction of the multiplied and the factored form of the transfer function.
  • Graphical output of a linear approximation and the smooth characteristic of gain and phase.
  • Axes of graphs labeled in powers of ten (frequency ), decibel (gain) und radiants (phase).
  • Arbitrary dimension of the analysis protocol through organization in text pages and scrollable graphical pages.
  • Easily understandable input format.
  • High execution speed, depending on the function to be analysed between 25 and 30 seconds (SX) or 15 and 20 seconds (GX)
  • Preservation of the last calculated data, which can be recalled at any time.
  • Special menu entry for multiplying and factoring a polynomial.

Sorry, there isn't gonna be more development, as I finished this project a long time ago (1995!!). Still, if you like it, feel free to drop my an email.
