Question I’ll get straight to the narrow point ahead: I’d like an expert’s opinion on the appropriate use of Bessel when considering a specific 4th order bandpass design. I don’t mind a more general …

I’ve been looking into reverse polarity protection and come across a lot of resources that recommend using a P-channel MOSFET with a Zener diode. Every single one of these circuits shows the MOSFET …

Charging while using the device reduces battery lifespan*. The charger gets confused in the Constant Current Phase because of the additional current drawn by the device. Windows OS and some laptop …

I am wondering about something really simple and silly. If functions generators have an internal series 50 Ω termination, then they would produce only half the set amplitude over a matched load. …

I have seen a table of opcodes for RISC-V instructions (for base I 32 bit ISA). I am working with a RISC-V core on FPGA and had BRAM for instructions set to all zeros. Does anybody know what happens …

I am using a 3.3V output of an NI controller over a coax transmission line. I have matched the termination resistor to the 50 Ohm source resistance. I need to use this output signal to control three …

As a novice electronics hobbyist, I have heard these terms and more being thrown around everywhere. At its root, I understand that they are all based on communication between devices, computers, …

While I (most of the time) know from experience what components are generally considered active or passive, I have yet to come across a satisfying definition. Why do we divide electrical components …

I have a couple of 12v batteries that I’d like to use to power a cooling apparatus while camping for several days. I also have a 15W solar panel I’d like to use to top-off the battery. Can I use the …

I want to connect the output from the audio jack of an iPhone to an Arduino. What voltage range can I expect to see on the audio lines from the iPhone? I assume that turning the volume up on the …

I’ve come across multiple mentions of switches described as 1NO1NC. They often described as having 2 options: ON/(OFF) and (ON)/OFF and from what I gather they have 3 terminals for wires: a NO …

I was just watching a mega factory video and wondered why they use an AC motor which requires a power inverter instead of DC which may be powered directly from their DC battery? Introducing an …

I have recently purchased an IKEA LED bulb with G9 fittings, to replace a halogen one. This one. The bulb is installed in a lamp with 3 other halogen G9s in a 3 + 1 configuration with a 3-state …

I am using the ATMEL SAM3x8e chip on an Arduino Due. I want to generate two pulses of frequency 100 kHz of the pattern shown below (1 period shown). For this I used TIOA8 and TIOA0 lines in the …

To give more detail, the toy I’m trying to modify has a reset PIN that I would like to tap remotely, as it goes to sleep after a few minutes and hitting that reset pin wakes it up. As such, while I do …

I have an OPA548 IC which is a high-power op-amp. I am using it in non-inverting amplifier configuration as shown in the schematic. The input signal is a ramp signal with low voltage 0.1 V and high …
