In the modulation system, the energy per bit-to-noise power density ratio \(\frac{{{E_b}}}{{{N_o}}}\) is(1) \(\frac{C}{N} \times \frac{{{f_b}}}{B}\)(2) \(\frac{N}{C} \times \frac{B}{{{f_b}}}\)(3) \(\frac{C}{N} \times \frac{B}{{{f_b}}}\)(4) \(\frac{N}{C} \times \frac{{{f_b}}}{B}\)Where:N = Noise power of thermal (W)B = Bandwidth (Hz)C = Carrier power (W) fb = Bit rate (bps)
