Some kind of integration will always be needed. If you cannot use an RC integrator, use a DAC and a up/down counter. As your input signal is high, count upwards high frequency pulses. When the input signal is low, count downwards. The output of the counter is supplied to a DAC. A low-pass filter smoothes the DAC output. Another way could b
Impedance of an inductor is wL ohms, for a pure sine wave. What is it's impedance to a square wave or a triangular wave signals.
The input sinewave may have varying frequencies. Would there be a problem if we convert it into square wave and take integral? I tend to believe that the resulting triangular wave would have varying amplitude Yes, you are right. The result of integration depends in its amplitude on the duration of the (...)

Is it possible to generate some sort of sine wave generation on FPGA. Using CORDIC algo is it possible. what shud we do if we want to generate analog signal on FPGA. is there any alternative. USMAN HAI
what does OA1 do? what does the transistor do (when it is on and off what happens)? what will happen to the circuit if we remove the capacitor? OA1 is connected is a way so that when the transistor is ON it will give a gain of -1 and -Vin will appear at the output and it will be integrated, thus the output of the integrat

I'm currenlty making a relaxation oscillator the produces a triangular wave. It is based on a charge pump technique, i.e. the upper current source charges the o/p capacitor (instead of the filter which is usually placed at the o/p of a CP in PLLs) then, after some time, the lower current source is activated while the upper one is dea

Hi all, I have read some very exciting stuff on this forum and i am hoping some of you electronics gurus can help me. I am building a pure sine wave inverter using a wien-bridge for my oscillator. Input voltage = 12v dc, Output voltage= between 30v and 60 v ac, output current not to exceed 2A. Frequency = 50hz. I have used a JFET in the negative f
Hi :-) If I want the 'electric current wave' to flow in only one direction, then I would a diode. While choosing a diode I would take into consideration several factors such as maximum current flow allowed, maximum power, etc. In the end, electronics is more or less about how to manipulate that 'electric current wave' to do different things. The

integration is used in low cost ADC that have the advantage of averaging the input with noise. look for "Integrate & Dump" type ADC for examples Accelerometers with true piezo-electric type use charge amplifiers to produce a voltage that changes with acceleration, A and vibration. Since we know Velocity, V is the Integral of "A" and Position is t

Hi, I have a stupid question about integrator noise.. Say an OTA has an input-referred noise Vn at it's positive input, and be connected into integrator, the transfer function (1/SRC) has infinite gain at DC, ideally. So what would input-referred noise Vn be at OTA's output? If I give input a rectangular wave, the OTA's output will be tri
