摘要： A bass enhancing apparatus and method for enhancing bass include generating harmonics of the bass when an input signal is reproduced using a miniaturized speaker. The bass enhancing method includes extracting a bass component of an input signal, generating harmonics of the extracted bass component, synthesizing the generated harmonic signals and the input signal, and outputting the synthesizing result to an output terminal. The generating of the harmonics includes compressing a dynamic range of an amplitude level of each harmonic component at a predetermined distribution ratio.

摘要： A pitch shifter capable of shifting an acoustic signal in pitch to an arbitrary level with a high degree of accuracy without any change in reproduction time, and also sufficiently reducing high-frequency distortion without being increased in size or speeded-up is provided. Stored in a filter coefficient string storage 6, four filter coefficient strings corresponding to four sub-filters produced through polyphase decomposition of a low-pass filter for 4-fold oversampling. Filter coefficient string selectors 5a and 5b select, based on the first and second bits of the decimal part of each of read addresses generated by the read address generators 4a and 4b, respectively, any one of the four filter coefficient strings stored in the filter coefficient string storage 6. Filter operation units 2a and 2b receive paired sound data strings, and carry out a filter operation by using the filter coefficient strings selected by the filter coefficient string selector 5a and 5b, respectively.

摘要： A supervisory system for a primary group digital transmission line wherein a terminal repeater transmits, over a supervisory line, address information designating an intermediate repeater and line within the intermediate repeater to be monitored while the line is in a normal, in-service condition. The terminal repeater and intermediate repeaters are cascade connected by way of the supervisory line. The terminal repeater and each of the intermediate repeaters include amplifiers that receive and send information along the transmission line, and have a monitor output. The monitor output is processed by an error monitor within the terminal repeater and in each of the intermediate repeaters and the results of the error monitoring provided to the supervisory line in response to polling by the terminal repeater.

摘要： There is disclosed a PLL circuit wherein a delay circuit (3') of a phase comparator (30') receives a supply current (IC) from a first variable current source (.PHI.IC) and changes a delay time (.DELTA.T) in negative correlation with the amount of the supply current (IC), and the first variable current source (.PHI.IC) changes the amount of the supply current (IC) to the delay circuit (3') in accordance with the indication of a control signal (C1) serving as a supply current control signal for a second variable current source (.PHI.IA) and a third variable current source (.PHI.IB) of a charge pump circuit (31). Changes in delay time of the delay device of the phase comparing device are adapted such that the delay time is constantly suitable as the amount of current of the phase comparison voltage signal of the charge pump circuit changes, permitting reduction in lock-up time.

摘要： In a variable frequency divider formed of a latch train, a frequency division ratio is set through selective invalidating a feedback signal to a first stage latch from the last stage latch. A size of MOS (metal-insulator-semiconductor) transistors for switching the division ratio is made larger than that of other MOS transistors in differential stages in the last stage latch circuit. Further, differential signals are transmitted as feedback signals to the first stage latch circuit. A F/(F+1) prescaler which operates stably with a low current consumption under a low power supply voltage condition is implemented.
