### How do you sketch a signal given by x(t) = A(t/T) for time period 0 to T? Does t/T simply denote that the signal covers entire duration of T?

Does t/T simply mean that the signal has magnitude A over the entire "T" duration? Or does it mean that it covers only a fraction? How will it look? I tried assuming A to be some magnitude ...

### Triangular waveform with low noise

I have a task to generate a triangular signal with variable amplitude and support. The figure shows the type of signal and what parameters I want to change (“d” and “o”). Moreover, I need to change ...

### AC DC adapter sawtooth current draw above rated value

I will be using AC DC wall adapter to power the flyback converter. Power adapter is rated 15V@3A = 45W. The question is, can I draw peaks over 3A if I stay below 45W on average? For example, with the ...

### Understanding sawtooth wave harmonics

I've been playing synthesizers for a while and I'm trying to understand their math and electronics better. The sawtooth is one of the three common waveforms on most subtractive synths. The waves are ...

### How to amplify sawtooth wave?

I have to amplify the sawtooth wave from 0-7V to 0-14V with its waveform intact. I tried to amplify the wave using op-amps, MOSFET but the waveform shape changes. I'm new to analog circuit design, it ...

### How to design a sawtooth wave generator? (Required specification of sawtooth wave 0-14V and 50kHz)

I tried using ICs like the ICL-8038 and the 555 time. It didn't work out because of the supply voltage constraint. I also tried using an op-amp (LTC6244) based circuit. It gave a distorted wave at ...

### Load curve control via differential pair

Last few weeks I have been designing a circuit, which is inputted with saw wave and outputs (amplification fairly linearly if possible) amplified voltage across two loads, where load voltage/current ...

### Sawtooth waveform used for wireless battery charging

Why don't we use sawtooth AC waveforms instead of the sinusoidal ones? Since the rate of change of voltage is steady for a purely resistive circuit the rate of change of current is costant-> linear ...

### Sawtooth VCO DC offset issues

[Apologies in advance for possible misuse of terminology. I don't have any formal education in EE and am mostly self taught, so I may be lacking in some fundamentals.] I am trying to design a discrete ...

### How to use an op-amp (that only uses ground and positive voltage to operate) to create a sawtooth/triangle wave generator?

The design I have in mind will be battery operated, so I have found the TL972 (Datasheet Here) which only operates from 0 - 12 V. What I want this op-amp to do is to create a sawtooth/triangle wave ...

### Miller integrator ramp generator?

In a page on Ramp Generators I found this peculiar circuit which is said to be superb in its linearity. But I can't make sense of it. It doesn't discuss any of the actual R and C values. I can see ...

### A sawtooth oscillator breaks down at higher frequencies

Here is a nice and straight-forward sawtooth oscillator that I learned from this video. It is simple and nice. When we come to higher frequencies though, I am dealing with very finicky adjustments ...

### What would be the simplest BJT based *linear* ramp generator?

Let's say I have a 74LS161 based counter, and I want an analog ramp generator which will linearly increase until the ripple-carry-output goes back down (so that the ramp goes up the entire time the ...
