The Siamese fighting fish (Betta splendens), commonly known as the betta, [2] is a freshwater fish native to Southeast Asia, namely Cambodia, Laos, Myanmar, Malaysia, Indonesia, Thailand, and Vietnam.
A betta fish's feeding habits will be based on the temperature of its environment. The tank water should be around 78 to 82 degrees Fahrenheit , according to Aquatic Veterinary Services.
A sweep generator is a piece of electronic test equipment similar to, and sometimes included on, a function generator which creates an electrical waveform with a linearly varying frequency and a constant amplitude. Sweep generators are commonly used to test the frequency response of electronic filter circuits.
The use of shallow water is also because fertilized eggs need to be aerated in order to hatch successfully. [3] Various stimuli have been shown to affect onset the construction of bubble nests, such as rapid changes in temperature, barometric changes, fluctuations in rainfall, various fish tank materials, and presence of other males or females.
A completely different approach to function generation is to use software instructions to generate a waveform, with provision for output. For example, a general-purpose digital computer can be used to generate the waveform; if frequency range and amplitude are acceptable, the sound card fitted to most computers can be used to output the generated wave.
Betta channoides is a species of betta endemic to the island of Borneo in Indonesia, where it is only found in the province of Kalimantan Timur. It is an inhabitant of the shallows of acidic brown-water forest streams. This species grows to a length of 5.0 cm (2.0 in). [2]
Betta coccina is a species of betta native to Peninsular Malaysia and Sumatra, Indonesia. [1] It grows to a length of 5.6 cm (2.2 in). It can be found in the aquarium trade. [2] Betta coccina, commonly known as the wine red betta or red fighting fish, is a species of freshwater fish in the family Osphronemidae. [3]
A variable-frequency transformer is a doubly fed electric machine resembling a vertical shaft hydroelectric generator with a three-phase wound rotor, connected by slip rings to one external power circuit. The stator is connected to the other. With no applied torque, the shaft rotates due to the difference in frequency between the networks ...
