An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave.
Elasticity of supply measures how the amount of a good changes when the producer hires more employees. Elasticity of supply measures how the amount of a good changes when the producer uses new materials. Elasticity of demand measures how the amount of a good changes when its price goes up or down. Elasticity of demand measures how the amount of a good changes when its distribution expands.
The slope of a linear supply curve is constant; the elasticity is not. If the linear supply curve intersects the price axis PES will be infinitely elastic at the point of intersection. The coefficient of elasticity decreases as one moves up the curve. However, all points on the supply curve will have a coefficient of elasticity greater than one.
