In this post we present modulation index formula and calculators for three different modulation formats: AM, FM and FSK. Amplitude Modulation Index Modulation index is a measure of the variation …
5G networks are being deployed around the USA and many other parts of the world. These networks will replace the older 4G systems. One of the biggest differences between 4G …
This calculator converts the Variation in Output Frequency (Hz/kHz/MHz/GHz) to parts per million (PPM) or parts per billion (PPB). It also calculates the Frequency Error (%). Enter: ? ppm to …
This tool converts from crystal oscillator stability in terms of parts per million (ppm) or parts-per-billion (ppb) to the equivalent frequency variation (Hz/kHz/MHz/GHz). It also calculates the change in period …
This tool calculates both the symbol rate and bandwidth for a Quadrature Amplitude Modulation (QAM) signal. Inputs required: Background QAM is a popular modulation format that’s used in many modern …
This tool calculates the Capacitor and Inductor values for a Bias Tee design. Enter the following: Formula The minimum value of Capacitance is C = 1/(2*π*f*Xc) The Inductance value is …
This calculator allows you to convert between dB and percent (%) values of Error Vector Magnitude. How to use the Calculator Enter either quantity and the other will be calculated. …
This tool converts from Error Vector Magnitude (EVM) to Signal-to-Noise Ratio (SNR). In order to calculate SNR the following are required: Formula SNR = – [PAPR + 20 * Log10 …
This tool converts the Root Mean Square value of Error Vector Magnitude (EVM) to its deciBel (dB) equivalent. It also computes the dB value from RMS. How to use the …
This tool converts from Wavelength in nm, um, mm, cm, m, inches or feet to Frequency in Hz, kHz, MHz, GHz. ? Frequency to Wavelength Formula Frequency f is given …
