A low value of peak factor (PF), the ratio of the range to the rms value of a periodic function, is desirable for radar, sonar, communications, and test signals. A previous paper [L. E. Hargrove, J. Acoust. Soc. Am. 92, 2312 (1992)] described low PF functions constructed from 1(less than or equal to)M(less than or equal to)101 harmonically related and equal-amplitude components with signs derived from spectra components of sinusoidally frequency-modulated sinusoids. In that paper, the flat and bandlimited spectra of the low PF periodic functions consisted of integer multiples n, 1(less than or equal to)n(less than or equal to)M, of a fundamental frequency f[sub 1]. In the present paper, similar low PF functions consisting of M equal-amplitude components with frequencies which are higher multiples n, 1
