CONCLUSION

In this article a simple yet accurate approximation for the error function erf(x) has been used to obtain closed-form expressions for the harmonic and intermodulation performance of SCM systems working at or near saturation. Also, closed-form expressions have been obtained for the carrierto-intermodulation ratio resulting from equal-amplitude equally spaced input modulation currents. The case of small amplitude modulating carriers was derived as a special case and the results obtained are in excellent agreement with previously published results.
