摘要： A controlling unit includes: a memory unit that stores information in which the multiple clock frequencies that satisfy conditions for predetermined reception interferences to a part of multiple carrier frequencies included in a band frequency of the broadcast wave are previously set so that not all clock frequencies satisfy the conditions for the reception interferences to the same carrier frequencies, the information indicating a relation between each clock frequency and the carrier frequency that includes the reception interference; a reception frequency setting unit that sets the carrier frequency to be received to the broadcast wave receiving unit; a clock frequency determining unit that refers to the information stored in the memory unit and determines a clock frequency that does not include a reception interference to the carrier frequency that is set by the reception frequency setting unit, the determined clock frequency being out of the multiple clock frequencies; and a clock frequency setting unit that sets the clock frequency determined by the clock frequency determining unit to the reference clock generating unit, so that the reference clock generating unit generates a reference clock having the determined clock frequency.

摘要： Surround-effect, providing no unnatural feeling to the listeners who sit next to each other under side-by-side basis through virtual sound sources, is realized. A surround left channel signal SL and a surround right channel signal SR are mixed with an adder 10 and are in monaural. A first monophonic signal and a second monophonic signal thus resulted are supplied to a virtual localization processor 12. A first virtual localization output of the processor 12 is supplied to a front left speaker SPL and a front right speaker SPR and a second virtual localization output thereof is supplied to a front center speaker SPC. In this way, virtual sound sources can be created at the right and the left to the listener 2. Similarly, virtual sound sources can also be created at the right and the left to the listener 3. Sound fields from the virtual surround sources are in reverse to the listener 2 and the listener 3. However, no substantial drawbacks caused by the reversal are observed because monophonic signals are reproduced as the surround signals in this embodiment. In this way, surround-effect with natural feeling can be achieved.
摘要翻译：实现了环绕效果，通过虚拟声源在并排的基础上彼此相邻的听众没有不自然的感觉。环绕左声道信号SL和环绕右声道信号SR与加法器10混合并处于单声道。由此产生的第一单声道信号和第二单声道信号被提供给虚拟定位处理器12。处理器12的第一虚拟定位输出被提供给前置左扬声器SPL和前右扬声器SPR，并且其第二虚拟定位输出被提供给前中心扬声器SPC。以这种方式，虚拟声源可以在右边和左边创建到听众2。类似地，虚拟声源也可以在右边和左边被创建到听众3。来自虚拟环绕声源的声场与听众2和收听者3相反。然而，由于在本实施例中单声道信号作为环绕信号被再现，所以观察不到逆转引起的实质性缺点。以这种方式，可以实现具有自然感的环绕效果。

摘要： A pulse width modulation circuit of the present invention includes: pulse generation means being provided with a first power supply and charged with a first current and a second current between which a constant current is distributed to turn ON/OFF a switching element, thereby generating a pulse from a first output section; pulse modulation means for controlling the charging while controlling a distribution ratio between the first current and the second current based on an input signal, thereby changing a pulse width of the output pulse; and first short circuit means for shorting the first output section with the first power supply when the pulse being output from the first output section transitions to a voltage of the first power supply.
