The 50-ohm impedance is standard in RF design, while 75 ohms is also used, so it’s important to understand the attributes of each and not confuse them. One of the issues that beginning electronic ...

Abstract: A generalized dispersion equation is derived featuring coupled mode theory, parity-time symmetry, and leaky wave antennas of arbitrary periodic modulation ... is first used to design a ...

The T4’s sensitivity rating is 102 dB/mW (with an impedance of 32 ohms), which on paper means that it’s a bit harder to drive to higher volume levels, but you’re unlikely to notice any ...

For that matter, what's an ohm? While impedance technically does matter, it's not quite as cut and dry as saying "speakers with X impedance should only be connected to receivers with Y impedance." ...

Since the Larmor frequency for this system is as low as 180 kHz, we are able to minimize the impedance of the transmit coil to 5 ohms rather than match to 50 ohms as is traditionally the case. This ...
