A constrained-envelope digital communications transmitter (10) places constraints on the envelope of spectrally constrained, digitally modulated communication signals (46) converted into diverse frequency channels (54) and combined into a composite signal (58). The envelope constraints achieve lower peak-to-average power ratio without allowing significant spectral regrowth. The composite signal (58) is applied to a plurality of cascade-coupled constrained-envelope generators (64). Each constrained-envelope generator (64) detects overpeak events (66) and configures corrective impulses (68) for the overpeak events (66). The corrective impulses (68) are distributed to the respective frequency channels (54) in accordance with a predetermined distribution profile (102) and are filtered into allocated shaped pulses (120) that exhibit a constrained spectrum. The allocated shaped pulses (120) are coherently converted into the respective frequency channels (54) and combined with the composite signal (58) to reduce an unwanted signal peak.

In the annealing step of the method for manufacturing a piezoelectric actuator, the annealing in conducted in two steps: a first annealing step; and a second annealing step conducted at a temperature lower and for a time longer than those of the first annealing step. With such treatment, first, grain growth inside the piezoelectric film can be sufficiently induced, while minimizing the diffusion layer growth, by the first annealing step conducted at a high temperature within a short interval, and then lattice defects in the particles can be sufficiently corrected, while preventing the diffusion layer growth, by the second annealing step conducted at a temperature lower and for a time longer than those of the first annealing step. Accordingly, the piezoelectric characteristic can be improved by sufficiently conducting annealing, while restricting the thickness of the diffusion layer to a range where the piezoelectric characteristic is not affected.
