2005年5月14日 · In this case, the given waveform is a sawtooth function that starts at 0, peaks at 10 in 1 second, and returns to 0 in another 1 second. The transfer function is given as S/S+1. To plot several cycles of the output response, we can use the inverse Laplace transform to convert the Laplace transform back to the time domain.

2021年7月23日 · I’ve been asked to create a sawtooth wave form with four input voltages. After doing this I then added a second op-amp to both change the range of the wave form from -/+5v to -/+2.5 and DC offset of 2.5v to create a wave form that ranges from 0v – 5v as required by the question. For the most...

2020年10月29日 · Homework Statement:: FIGURE 2(a) shows a ‘black box’ that is to partially synthesise a ‘sawtooth’ waveform of FIGURE 2(b) by using the Fourier series algorithm: Relevant Equations:: v(t) = 2/pi(sin.omega.t) Hi I received some great help yesterday and i was hoping someone would be able to help me out again today

2018年9月12日 · So just start with a summing amplifier stage to add up the 4 input waveforms. That will give you an approximation of a sawtooth waveform, but with too large an amplitude and centered at 0V instead of running 0V to 5V as shown in the graph. Then what can you do to offset the output waveform in the positive direction to get closer to the final graph.

2012年5月2日 · In practice, both the capacitor and the voltage generator have some resistance and some inductance, and the voltage generator is limited in the amount of current it can supply. These non-ideal elements will determine exactly what the waveform looks like.

2007年11月28日 · In summary, the conversation revolved around finding a simple circuit that can generate a backwards sawtooth waveform using op-amps. Suggestions included using a traditional sawtooth with inverted and offset signals, and using a single 8-bit downcounter with an R-2R ladder DAC configuration.

2012年1月6日 · A Sawtooth Wave Generator works by charging a capacitor at a constant rate through a resistor. Once the capacitor reaches a certain voltage, it discharges rapidly, creating the sawtooth waveform. The frequency and amplitude of the waveform can be adjusted by altering the values of the resistor and capacitor.

2020年10月29日 · And of course it doesn't include the offset and scaling yet to give you the 0-5V sawtooth waveform that you are asked to produce with your circuit: When I use the FS from Wikipeda for a forward sawtooth waveform (including the offset and scaling for the Amplitude = 5V), it looks a lot closer once the initial startup phase is done...

2009年11月15日 · By passing the sawtooth waveform through a low-pass filter, the high-frequency components will be attenuated, leaving behind the lower frequency components that make up a sinusoid. This process can be achieved by using a combination of resistors, capacitors, and inductors in a specific configuration, such as an RLC series or parallel circuit.

2021年7月28日 · The question about the inversion or whatever of the signal was in a different...In summary, the question wanted a sawtooth wave form that ranges from 0v – 5v, and the circuit created by the expert is close, but the second op-amp "flipped" the wave form.
