Castrated males are called wethers. Goat meat from younger animals is called kid or cabrito (Spanish), while meat from older animals is known simply as goat or sometimes called chevon, or in some areas mutton (which more often refers to adult sheep meat).
Function Generators. A function generator is a signal source that has the capability of producing different types of waveforms as its output signal. The most common output waveforms are sine-waves, triangular waves, square waves, and sawtooth waves. The frequencies of such waveforms may be adjusted from a fraction of a hertz to several hundred kHz.
1 An electric generator rotates a coil in a magnetic field, inducing an emfgiven as a function of time by $\varepsilon = NABw~sin\omega t$.  Generators supply almost all of the power for the electric power grids which provide most of the world's electric power.
