Abstract:
1. A communication functionality inspection method performed in the electronic circuit comprising a first substrate; a first transmission coil that is formed by a wire and transmits a signal; a first transmission circuit that outputs a signal to said first transmission coil; a first reception coil that is formed by a wire at such a position that the first reception coil is inductively coupled to said first transmission coil and receives the signal from said first transmission coil; a first reception circuit that receives the signal from said first reception coil; a first determination circuit that compares data input to said first transmission circuit and data output from said first reception circuit; a second substrate; a second reception coil that is formed by a wire at such a position that the second reception coil is inductively coupled to said first transmission coil and receives the signal from said first transmission coil; and a second reception circuit that receives a signal from said second reception coil, wherein the second reception coil and the second reception circuit are mounted on said second substrate, wherein the first transmission coil, the first transmission circuit, the first reception coil, the first reception circuit and the first determination circuit are mounted on said first substrate, wherein a communication functionality between said first substrate and said second substrate is inspected by said first determination circuit comparing a signal transmitted from said first transmission circuit and a signal received by said first reception circuit, wherein said first transmission circuit is capable of setting a temporal variation rate δ of a current applied to said first transmission coil at any value, said method comprising setting the temporal variation rate δ
