摘要： An impulse noise reducer detects impulse noise in an audio signal by detecting and smoothing the high-frequency amplitude of the audio signal, attenuating the non-smoothed amplitude according to the smoothed amplitude, and comparing the attenuated amplitude with a threshold. Impulse noise is discriminated from high-frequency audio components because the latter tend to occur in longer-lasting bursts and are therefore attenuated more strongly. The impulse noise reducer is simplified because it does not have to perform intermediate-frequency signal processing, and its sensitivity is not affected by adjacent-channel signals because these signals are substantially absent from the audio signal. The impulse noise reducer can be implemented by digital signal processing, and is suitable for use in a medium-wave AM audio broadcast receiver.
摘要翻译：脉冲噪声降低器通过检测和平滑音频信号的高频振幅来检测音频信号中的脉冲噪声，根据平滑的幅度衰减非平滑幅度，并将衰减幅度与阈值进行比较。脉冲噪声与高频音频分量区分开来，因为后者往往会发生在持续较长的脉冲串中，因此会更强烈地衰减。由于不需要执行中频信号处理，所以脉冲噪声减少器被简化，并且其灵敏度不受相邻信道信号的影响，因为这些信号基本上不存在于音频信号中。脉冲减噪器可以通过数字信号处理实现，适用于中波AM音频广播接收机。

摘要： An impulse noise detector detects impulse noise in an audio signal by filtering out the audio components of the signal, then comparing an envelope of a filtered signal with a threshold obtained as a moving average of the envelope. Short-duration impulse noise is thereby detected without detecting tone bursts and other fast-rising signals of longer duration. The envelope may be taken directly from the filtered signal, or from a difference signal obtained from a preliminary envelope of the filtered signal, to emphasize impulse noise when distorted audio components leak into the filtered signal.

摘要： A disc apparatus includes a readout unit, an audio signal output unit, a memory, a switch, and a controller. The readout unit reads out data from a disc wherein the data includes at least digital audio data. The audio signal output unit produces an audio signal output in accordance with the digital audio data. The memory stores the digital audio data read from the disc by the readout unit. The switch switches the digital audio data supplied to the audio signal output unit between the digital audio data stored in the memory and the digital audio data currently being read by the readout unit. Furthermore, the controller controls the readout unit and the memory so that, prior to a playback start operation, the digital audio data of a first predetermined period from a beginning of at least one program is read out by the readout unit and stored in the memory; controls the switch so that, at a beginning of the playback start operation, the audio signal output unit produces the audio signal output based on the digital audio data stored in the memory; and controls the switch so that, a second predetermined period after the start operation, the audio signal output unit produces the audio signal output based on the digital audio data currently being read out by the readout unit.

摘要： A magnetic recorder/reproducer converts two-channel analog signals into digital signals by a sample-and-hold/A-D converter circuit (3) and controls addresses in a memory circuit (4) by a memory address control circuit (5), to distribute the digital signals into odd sample groups and even sample groups per each channel for arraying the odd sample groups and the even sample groups of the same channel in alternate scanning intervals, thereby to write the same in the memory circuit so that the odd samples and the even samples of the same channel are arrayed in positions separated from each other along the direction of scanning by rotary heads (10, 11). The digital signals thus permutated are modulated by a modulation circuit (7), to be recorded in a magnetic tape by the rotary heads. The digital signals reproduced by the rotary heads are demodulated by a demodulation circuit (14), to be stored in a memory circuit (15). A memory address control circuit (16) controls addresses so as to permutate samples of the reproduced digital signals stored in the memory circuit to be in the original array thereof. The reproduced digital signals read from the memory circuit are converted into analog signals by a D-A converter (18), to be outputted through a low-pass filter (19).
