Communications Formulas
Communications formulas relate bandwidth, data rate, and signal-to-noise ratio to channel capacity and link reliability. These calculators help you budget gains and losses across a transmission path. They are essential for wired and wireless link planning.
Communications Formula Calculators
- UART Baud Rate Error Error% = |actual − target| / target × 100
- RS-485 Termination Resistor R = Z_cable
- RS-485 Bias Resistor R_bias = (Vcc − V_diff_min) / I_bias
- Shannon Channel Capacity C = B × log₂(1 + SNR)
- Bit Error Rate (BPSK) BER = 0.5 × erfc(√(Eb/N0))
- Wireless Link Range d = f(Ptx, Gtx, Grx, sensitivity, freq)
- Manchester Encoding Bandwidth BW = 2 × bitrate
- I²C Pull-up Resistor R_max = t_rise / (0.8473 × C_bus)
