The duty and the frequency were adjusted by changing the time constant and the way of charging and discharging of the capacitor, the width of frequency was adjusted by using different capacitors provided with multiple switch, the amplitude of output voltage was adjusted by sampling voltage and using in-phase amplifier circuit,the ability of driving loads was raised, the circuit can be used as squarewave signal generator whose frequency and amplitude can be adjusted. The final simulation results of Multisim 10 and the tests of applicable circuit show that the performance indicators of the circuit meets the design requirements.

Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram.

Debussy是NOVAS Software, Inc(思源科技)發(fā)展的HDL Debug & Analysis tool,這套軟體主要不是用來跑模擬或看波形,它最強(qiáng)大的功能是:能夠在HDL source code、schematic diagram、waveform、state bubble diagram之間,即時(shí)做trace,協(xié)助工程師debug。 可能您會覺的:只要有simulator如ModelSim就可以做debug了,我何必再學(xué)這套軟體呢? 其實(shí)Debussy v5.0以後的新版本,還提供了nLint -- check coding style & synthesizable,這蠻有用的,可以協(xié)助工程師了解如何寫好coding style,並養(yǎng)成習(xí)慣。 下圖所示為整個(gè)Debussy的原理架構(gòu),可歸納幾個(gè)結(jié)論:

This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm is based on the interpolation technique for two correlation values in the frequency and phase domains. This simple interpolation technique can significantly improve frequency and phase resolution capabilities of the proposed technique without increasing the number of the correlation values. In addition, the overall block diagram of a digital communications receiver for DVB-RCS is presented, which was designed using the proposed estimation algorithms. Index Terms—Carrier phase estimation, DVB-RCS, frequency offset estimation, interpolation, joint estimation, MF-TDMA.
