IC Calculator

This article features calculators of:

  • Simple calculator
  • Resonating frequency.
  • Impedance conversion.
  • Transmission line RLGC parameters from S parameters.

Simple Calculator with mathjs

Usages includes:

  • Direct calculation: (1+2) 3/4 (where space denotes multiplication)
  • Variable definition: x=2
  • Function definition: db(x)=20 log10(x)
  • Matrix calculation: det([1, 2;3, 4])
  • Symbolic calaulation:
    • a=simplify('x+x')
    • a.evaluate({x:2})
    • derivative('log(x)','x')

Refer to mathjs documentation for detailed usages.
