Hi, I am working on a feedback circuit. I am using a sinusoidal signal to excite a sensor. I need to control the output voltage in the range of 100-200mV. So I am working with an AGC cirucit which is a real complicated one. So I have thought of using a simple diode clamping circuit for this but as it generates a square wave. I need a sine (...)

I know that I need to use a low pass filter, however I am not sure what values of R and C, or L and C to use, cuttoff frequency, etc. I am new to low pass filters and need (...)
Yeah a switched capacitor bandpass filter is one neat possibility. You just have to generate a clock to select the center frequency. Can u give me some site where it can show me the connectivity of switched capacitor bandpass filter with my square waveform

Dear friends, I've nearly finished my ultrasonic cleaner project. I've tried to drive 60W transducer with square wave from H-bridge based on IR2110 and PWM, but I think sinus wave will be much more efficient for this operation. So how can I convert my square wave to sinus wave with a basic way? with kind regards,
Hy 2 all; I am designing a DC-AC converter . I am willing to produce the output nearest to sine wave ( or it could be modified sine wave) I have done PWM DC-AC converter. My Problem is that i have designed my boost ckt with L=10mH AND C=220uF AND R=110 DIODE=10A04 AND PIC=16F877A MOS=IRFZ44N 66931 My PIC code using
Linearity can be expressed by the amplitude of fundamental freq. component (freq. you want) relative to adjacent second harmonic freq. component. Linearity is the best if your oscillator has only single fundamental component.. You can make a simple sinusoidal oscillator using a 555 oscillator and simple LPF.. Depending on frequency.. This
My question is why you choose just 8038 , there is much simplier IC for this like 555 or other
How often do you want your 5 cycles? Do you want the cycles to be switched on at a certain part of the waveform. It looks like pin 3 controls the output level, so link it to V cc with a high value resistor. Then a 555 timer chip can be used as a monostable, if you set its time to (250KHz = 4 microS period X 5) to 20 microseconds to the output of t
You can use a comparator and connect a variable DC voltage to one of the inputs to vary the trigger point on the sine wave. Use the comparator output to trigger a one-shot such as with a 555 or a CD4098 to get a fixed pulse-width output.
How can one get the amplitude spectrum of a sine wave? For example, have a look at The amplitude spectrum of a sine wave is a spike in amplitude. How can I get it using calculations? Do I just get the fourier transform of the sine wave and then d

For a sine wave generated by PLL, can anyone tell me how to calculated its SNR? In the frequency spectrum , I can not distingguish what's the signal and what's the noise because the signal spectrum is not a single line but with a lot of phase noise. As a common method, in FFT analysis, we often pick some bins beside the signal and add them toget

how to extract the DC component of the sine wave signal V+V0coswt ?? that is : the input signal is V+V0coswt , when it passes through the system I designed, the output signal is V, or proportianal to V? one may say a lpf will do this work , but if w is relatively low ,for example in the range of 100Hz ? such a lpf is not easy
