a通过低通滤波器将SPWM信号的谐波全部滤出掉,只剩下其基波分量,即就是系统所需要的正弦波信号。 Filters out completely through the low pass filter the SPWM signal overtone, is only left over its fundamental wave component, namely is the sine wave signal which the system needs.[translate] ...

In addition, as a result of system transition condition simulated program and so on the EMTP unceasing development, its function is day by day formidable, but also may use them to carry on the power equipment, the part modelling and the electrical power system overtone analysis. [translate] a...
After the PIC16F76 monolithic integrated circuit uses its interior CCP the module the PWM pattern to have the output signal actuation the level electric circuit, then the output signal filters out completely through the low pass filter the SPWM signal overtone, is only left over its fundamental ...
Absorption band 2 at around 1700 nm was likely due to aromatic hydrocarbons typically found in terpenoids due to the presence of CH stretching and combination bands of the first overtone6,45. As NIR combination bands are non-specific to compounds due to similarities in functional groups, unique ...
Lignin could be identified at 4015–4022, 4392–4412, and 5776–5796 cm−1 by its stretching vibration (O–H, C–H, C–O, and C–C) and the overtone stretching band of O–H [24, 38]. Ash, an inorganic component, could not be detected directly using NIRS, but could be ...

However, their interface itself is still abstract and not very informative about the kind of sounds it produces. For this reason, in this paper we present the concept and rst prototype for an augmented digital handpan. In our concept we use Leap Motion to capture strokes on a plexiglass dome...
