SOLUTION: Providing: ...
In the CE (common emitter) amplifier composed of NPN transistor, when the input signal is a sinusoidal waveform of 1 kHz and 5 mV, the output voltage waveform has a distortion of bottom flattening. This distortion is ( ). A、saturation distortion ...
Distortion detector and high-frequency amplifier therewithdoi:CN1531193 A一种失真检测装置,将产生于输入的第1信号的第1频带中的第1失真分量与相关的第2失真分量产生的第2频带中的第2信号,从该第1信号分波. One kind of distortion detection means, will be generated at the input of the first signal in ...
While electroacoustic components can exhibit wide variations in frequency response, DAC and amplifier components should be flat. RegardingDACs, the output should always be completely flat across audible frequencies, even in low-cost designs. The conversion from digital to analog in hardware is a strai...
PROBLEM TO BE SOLVED: To obtain a power amplifier for high frequency which eliminates the need to add as a different circuit a circuit for control over impedance to higher harmonics, as viewed from a preceding stage high-frequency power amplification part and impedance to higher harmonics, as vi...
'Frequency Gain' refers to the variation in gain of an amplifier over different frequencies. It is the measure of how the gain of an amplifier changes as the input signal frequency varies from low to high frequencies. AI generated definition based on: Electronics and Communications for Scientists...
(in our case approx. 17Hz). Synchroconverters can be used but they require the parallel operation of synchronous compensator and also create very high distortion of the input current. That means the only choice is usingPWM, which comes in two configurations. Its rectifier can contain diodes, ...

The amplifier sampled data at 1200 Hz with a high-pass filter with a cut-off frequency of 0.1 Hz and notch filters centred at 50 Hz harmonics to remove power-line noise. The data were subsequently re-referenced using a local scheme whereby the signal for each electrode was adjusted ...
