Thankfully
others can understand the usefulness of ChatGPT as an assistant.
What is describe there is a good use case because validation of the output is built into the process, and it can actually save you time. No argument there.
My larger point is that it's not good for any situation in which you need an answer that isn't somewhat self-validating (like code) or you don't already know the answer.
For example I just asked it to design a crossover circuit... it contradicts itself in the same response.
- Choose filter types: There are several types of filters that can be used in a crossover circuit, including first-order (6 dB/octave), second-order (12 dB/octave), third-order (18 dB/octave), and fourth-order (24 dB/octave). For this design, we will use a second-order crossover with a 12 dB/octave slope.
- Determine crossover components values: For a second-order crossover, you will need a capacitor and an inductor for each driver. The capacitor is used to block low-frequency signals from reaching the tweeter, while the inductor is used to block high-frequency signals from reaching the woofer. The values of the components are calculated using the following formulas:
Capacitor value (in microfarads) = 1 / (2 * pi * crossover frequency * tweeter impedance) Inductor value (in millihenries) = 0.159 / (crossover frequency * woofer impedance)
Assuming a tweeter impedance of 8 ohms and a woofer impedance of 4 ohms, the capacitor and inductor values for a crossover frequency of 2,500 Hz are:
Capacitor value = 3.3 microfarads Inductor value = 1.3 millihenries
- Assemble the crossover circuit: Once you have determined the values of the components, you can assemble the crossover circuit. Place the capacitor in series with the tweeter and the inductor in series with the woofer. Connect the two branches of the crossover in parallel to the amplifier output.
So which is it? One component per driver, or two? I'm no EE and maybe this is technically right... but it seems wrong, even self-contradictory, and it's definitely confusing. If it's wrong, and I don't know that, I'm going to put together a really s***y speaker, best case scenario. Worst case scenario I cost myself $100s by destroying drivers because I used ChatGPT and not a normal crossover calculator.
