20110291715 | PHASE ADJUSTMENT CIRCUIT - In a phase adjustment circuit that divides the frequency of a double-frequency clock to obtain a 50% duty-cycle clock, a first 1/2 frequency division circuit having a phase inversion function generates an intermediate reference clock apart in phase from both a phase reference clock and a phase-adjusted clock. A first phase control circuit controls the phase of the intermediate reference clock to be in a desired phase state with respect to the phase reference clock.

Thus, when the phase-adjusted clock is adjusted to be close in phase to the phase reference clock, the phase difference between these clocks can be determined correctly and stably even if it varies due to clock jitter. | 12-01-2011 |

20090052695 | Signal processing device, signal processing method, and program therefor - A signal processing device includes a bass signal extractor, a harmonic wave generator, a level detector, and an adjustment controller. The bass signal extractor first extracts a bass signal from an input audio signal. Natural-sounding bass enhancement is achieved as a result of the adjustment controller boosting the bass signal level until the level detector detects the bass signal level at a set level. For input bass signal levels higher than the set level, bass is enhanced virtually using a harmonic signal generated from the bass signal by the harmonic wave generator. As a result, the disadvantages of the boost method and the virtual signal enhancement method are mutually compensated for, and synergistic advantages for bass enhancement are obtained. | 02-26-2009 |
