Baluncore's latest activity
-
Baluncore replied to the thread Interpreting VIA PCB characteristics through TDR and TDT.This LTspice model is sufficient to model the signal passing through a via. T1 is the line on one side of the PCB. T2 will become the... -
Baluncore replied to the thread Interpreting VIA PCB characteristics through TDR and TDT.Tektronix produced this 114 page reference. Time-Domain Reflectometry Measurements, by James A. Strickland... -
Baluncore replied to the thread Interpreting VIA PCB characteristics through TDR and TDT.Here is a simple TDR simulated in LTspice. Remove the .txt extensions from both files, then run the LTspice file.asc Start by changing... -
Baluncore replied to the thread Interpreting VIA PCB characteristics through TDR and TDT.TDR is a plot of impedance (driver voltage) against reflection time. Z = √( L / C ) You cannot say if it is the inductance or the... -
Baluncore reacted to berkeman's post in the thread Interpreting VIA PCB characteristics through TDR and TDT with
Like.
What you show is a 3-layer PCB, which is not used in practice. This point made by @Baluncore should be emphasized. It is generally a... -
Baluncore replied to the thread Engineering Half wave voltage doubler.Then you would have seen a "tripler" circuit in a CRT monitor, driven by the horizontal output transformer... -
Baluncore replied to the thread Engineering Half wave voltage doubler.That is because the output voltage is to be negative relative to ground, as in the diagram in post #1. I think in post #1, they are... -
Baluncore replied to the thread Interpreting VIA PCB characteristics through TDR and TDT.You have two tracks with known impedance, joined through the PCB by a short cylindrical via. The via will probably not match the... -
Baluncore replied to the thread Engineering Half wave voltage doubler.Welcome to PF. This is a problem of understanding how the circuit works, assuming perfect components. If you specify the frequency... -
Baluncore replied to the thread Controlled (Thyristor) Three-Phase Full-Wave Rectifiers in LTspice.I have not got it running yet. Your gate bias was a problem. See attached. -
Baluncore replied to the thread Undergrad DH Mt Bike - Optimizing Drop Landing Ramp Profile.In a way, but not to reduce rolling resistance. There is no fear of flipping backwards since you regulate body position and pedal force... -
Baluncore replied to the thread Undergrad DH Mt Bike - Optimizing Drop Landing Ramp Profile.Flipping over backwards is totally unnecessary. As an amateur cyclist wearing cleats, I could lift the front wheel just off the ground... -
Baluncore replied to the thread Undergrad DH Mt Bike - Optimizing Drop Landing Ramp Profile.I think you assume a front wheel hop from a body bounce, while holding the handlebars. I assume the front wheel lifts due to pedal... -
Baluncore replied to the thread What should sit beside a physics equation?.Take a look at a book of physics formulas. https://www.amazon.com.au/dp/B0BDXFMG5M/
