Example Sentences

The attenuation constant for the phantom muscle tissue is αₘ = 10.0 nepers/m.

Values of b, the amplitude attenuation constant, are given for various materials in Table 1.1. Having dimensions of [length]⁻¹, it is usually measured in nepers per centimetre (Np cm⁻¹).

The unit of α is nepers per meter. It can be easily seen that if a line has an attenuation constant of 1 neper/m, a unit amplitude voltage wave will reduce to e⁻¹ over a distance of 1 meter.
