电学计算器

欢迎使用！ V vs. W/dBm: Vp = V * CF, (CF = Crest Factor) Vp-p = V * CF * 2 dB = 20 * log10(V/V(ref)), (V(ref) = Reference Voltage) W = V * V / Ω (Ω = load) dBm = 10 * log10(W/1000) dBW = 10 * log10(W) A = V / Ω 输入任何一个值，得到所有其他值。 Error(%) -> Error(dB): Voltage: EdB = 20 * Log10(1+E%/100) Power: EdB = 10 * Log10(1+E%/100) Error(dB) -> Error(%): Voltage: E% = (power(10, EdB/20) - 1)*100% Power: E% = (power(10, EdB/10 - 1)*100% Δ“用于微调输入值。 PM(rad) vs. dB Jn = BesselJ(rad,n) 1st(dB) = 10 * (Log10(J1*J1) - Log10(J0*J0)) 2nd(dB) = 10 * (Log10(J2*J2) - Log10(J0*J0)) 输入任何一个值，得到其他值。 保存历史记录，可来回调看。
