Explain the operation of a piezoelectric sensor and its applications in electrical engineering, such as vibration monitoring and pressure sensing.Discuss the principles of operation of a phase-locked loop(PLL)and its applications in frequency synthesi...
Many were simple harmonic progressions as described above; others were rudimentary attempts at multisampling, whilst others attempted to emulate oscillator sync sweeps and PWM (pulse-width modulation) effects. Because the wavetable sweeping was so audibly stepped, the latter two weren't entirely convinci...
4. Wide voltage range. The output voltage of the switching power adapter is adjusted by the duty cycle of the excitation signal, and the variation of the input signal voltage can be compensated by frequency modulation or widening. In this way, it can still guarantee a more stable output volt...
PWM stands for pulse width modulation. A motherboard controls speed by intermittingly sending a current pulse to the fan. With a three pin connection, two are voltage and one is a speed sensor. Most motherboards have 4 pin for the cpu at least. Normally, if you put a three pin there...
