In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
Each shift in offset voltage or current often lasts from several milliseconds to seconds, and sounds like popcorn popping if hooked up to an audio speaker. [ 2 ] Burst noise was first observed in early point contact diodes , then re-discovered during the commercialization of one of the first semiconductor op-amps ; the 709. [ 3 ]
With no signal present on the input, the noise and distortion of the receiver are measured at a convenient level. A signal is applied to the input such that the output increases by 12 dB. The level of the signal needed to produce this is noted. In this case, it was found to be 0.25 microvolts.
Audio signal flow is the path an audio signal takes from source to output. [1] The concept of audio signal flow is closely related to the concept of audio gain staging; each component in the signal flow can be thought of as a gain stage. In typical home stereo systems, the signal flow is usually short and simple, with only a few components.
Line out provides an audio signal output and line in receives a signal input. The line in/out connections on consumer-oriented audio equipment are typically unbalanced, with a 3.5 mm (0.14 inch, but commonly called "eighth inch") 3-conductor TRS minijack connector providing ground, left channel, and right channel, or stereo RCA jacks.
Oklahoma City, OK: No. 17 in 2025, up 21 spots from 2024. Birmingham, AL: No. 20 in 2025, up 21 spots from 2024. Cities that saw the biggest losses. Memphis, TN: No. 42 in 2025, down 30 points ...
In audio equipment noise is a low-level hiss or buzz that intrudes on audio output. Every piece of equipment which the recorded signal subsequently passes through will add a certain amount of electronic noise the process of removing this and other noises is called noise reduction .
Stockton took over in the second half and helped rejuvenate a Georgia offense that scored only three points in the entire first half, before having to leave the game himself following a hard hit.
