That means 13 microSeconds going down and 13 microseconds going up. You need a slower Pwm frequency or a faster op amp.

Also, what is the function of Q2 in this circuit? Can anyone tell me why the waveform is lean towards the back?

Feb 18, 4. Feb 16, 1. This is a very large increase in output impedance, and introduces a phase shift and low pass filter into the second opamp’s feedback loop. Feb 16, 2. Looking at your o-scope output, my calibrated eye is fairly accurate and the datasheet is exactly right.

Feb 16, 3. Your name or email address: After I modified the circuits, which Q1 was replaced with 47K resistor and I put diode between pin 7 and the base of Q3. Feb 6, 2. The datasheet says the slew rate is 0. Can anyone tell me what this cable assy is for? I have an original circuits as follows: Quote of the day.

View attachment Why does its output perform like this way, not dc voltage output? Thank you for your help. No, create an account now. You May Also Ratasheet I don’t know if this saturated and the top was cut since this is very big output gain. Many of these devices are operated by non-tech-savvy users who may not know how to maintain their own device security.

The output was as follows. Digital Signal Processing in Scilab: So, each valley is about 66 microSeconds apart at 15kHz. LMD Datasheet is attached. Aug 1, 7, 2, Posted by gaya3eeee in forum: How does this happen?

Note that low power devices are usually slow speed devices. Posted by Faizan Ahmad in forum: Why did you replace an emitter-follower pull up device with a 47K resistor? Posted by rezash in forum: Posted by sarkarnov in forum: So, let’s take 13 microseconds 0. km258d

Yes, my password is: View attachment Figure 3 flyback circuit provides power input for the circuit in Figure 2 When I measured the pin 7 output at its original circuit in Figure 1, its output is dc voltage around That means, according to my calibrated eye, the valley is about 25 microsecond wide. Nov 23, 8, 6, View attachment Figure 4 Modified circuit Here is the modified circuit output, which is not my expectation. Do you already have an account?
