## synchronizing sine wave

Hii I have a sine wave of freq 50 Hz stepped down from a transformer and a triangular wave generated from IC8038 with freq 3KHz now i have to synchronize these two waves so that my pulse width modulation wave obtained from these two waves on inputing to a comparator has a quarter wave symmetry. Please HELP You

## HELP: Circuit Diagram DC inverted to AC (inverter)

im working on this.very hard to part require the generator can be manually set frequency modulation (Mf) and amplitude modulation (Ma). which mean the sine wave generator and triangular wave generator have to be variable frequency and amplitude.the mosfet transistor is not easy to implement in H-bridge.when u come to practical,it is

## Modulation frequency and Modulation Amplitude

Hi,happy new year 2010. As my attachment below,there are triangular waveform circuit and sine waveform circuit.The frequency and amplitude can be variable.The modulation frequency(Mf)=9,and the modulation amplitude(Ma)=0.8. so my question is,how to maintain the modulation Frequency(Mf)=9 since my sine waveform (...)

## Phase modulation of sine waveform in VHDL

Hi, I'm currently in the process of developing a control scheme for a custom power device using FPGA. The control scheme processes the error voltage through a PI controller whose output (PI output) is used to phase modulate the sinusoidal waveform (50 Hz). The phase modulated waveform is then compared against a triangular carrier wave to generate
