JAVASCRIPT CALCULATORS

• Resonance frequency of an L/C circuit, calculate F, C, L
• Impedance of a capacitor or inductor
• Two resistors or inductors in parrallel or two capacitors in series

Electric and magnetic fields:

• Path loss in free space for space communications
• Gain of a parabolic antenna
• K-factor of an antenna (for conversion from dBuV to fieldstrength)
• Conversion of dBm from a reception antenna to power density / fieldstrength
• Field strength of a transmitter in free space
• Magnetic field strength close to a loop antenna

Conversions between dB's volts, ampere, watts etc.:

• volts, ampere, watts to dB values and vv
• dBuV, dBuA to dBm and vv

Noise:

• Galactic noise

Various:

• Clock and stopwatch
• Windings on a toroide
• Thevenin, voltage divider
• Body Mass Index calculator

Specific:

• Limits lin and log with frequency
• Limits per oct
• EMC test setup with long wire
