The basis of the spectral correlation methods is based on the cyclostationary characteristic of the BOC signal, so that the parameters of the carrier, square wave, and pseudo random sequence can be estimated.
Power (W), Aerobic Power ([VO.sub.2]), and Heart Rate (HR) Averages at Anaerobic Thresholds Observed in Progressive and Square Wave Tests.
The first block composed of a square wave DC source (TLC555) used as a Schmitt trigger and a driver TC4421 is replaced by a half-bridge converter in order to generate +15 V DC, 100 kHz power supply.
Figure 3b shows a representation a wave at the resonant frequency where the combination LC works as a filter where attenuation of harmonics reflect one sine wave with the same fundamental frequency of the square wave, this can be expressed as the following Fourier series:
The square wave signal generator (G) injects a high frequency signal into the sensor.
Finally, the shape of the force profile will likely vary from the modulated square wave, so both sinusoidal and square waves are compared in terms of OLEA excitation effectiveness in the paper below.
For example, in Figure 2, this circuit only adds a LC resonant at 3[[omega].sub.0], and in Figure 3, though the wave drain terminal voltage waveform has a little difference compare to the ideal square wave, but in inhibition of drain terminal [V.sub.max] has significant performance.
In case the efforts are directed to track a fixed square wave signal in the presence of disturbances, the initial conditions of the system we reset to [x.sub.1](0) = 0.4, [x.sub.2](0) = [x.sub.3](0) = [x.sub.4](0) = 0.
In square wave inverters usually with single pulse scheme all the odd harmonics are present [8].Modified sine wave and square wave form voltage are might be acceptable for medium and low power applications, but for high power applications, sinusoidal and less distorted voltage waveform is required [9].
Electronically controllable functional (triangular and square wave) generators are widely employed in many analog and digital communication subsystems (clock generation, pulse width modulation, TTL or CMOS logic, DC-DC, AC-DC converters, etc.) [6], [7].
