Using MathCAD to draw the error isogram of Voltage-controlled VoltageSource(VCVS) 2nd-order high-pass filter's parametric equation,after analysis and research,the paper puts forward an optimized design scheme: firstly,selecting two capacitances C1 and C2,making C1= C2;and then calculating the val...
These frequency transformations include lowpass-bandpass and lowpass-bandstop frequency transformations keeping the same bandwidth as that of the prototype lowpass filter. It is also shown that the horizontal second-order modes are invariant when only horizontal transformation is applied, and the ...
Second-order nonlinear optical processes convert light from one wavelength to another and generate quantum entanglement. Creating chip-scale devices to efficiently control these interactions greatly increases the reach of photonics. Existing silicon-base
idea. However, the integrating network only forms a first-order highpass filter in the preamplifier. The first-order highpass filter filter having an attenuation of -20 dB/decade is not good enough to suppress the high-intensity low-frequency interference. In order to obtain a desired better ...
Using bifurcations in the determination of lock-in ranges for third-order phase-locked loops The dynamics of a PLL is described by an ordinary nonlinear differential equation, with order one plus the order of its internal linear low-pass filter... JRC Piqueira - 《Communications in Nonlinear Sc...
Block Diagram Of A Second-Order Modulator The modulator shifts the quantization noise to high frequencies, as shown in Figure 46; therefore, a low-pass digital filter should be used at the output of the device to increase the overall performance. This filter is also used to convert from the...
