There are three types of asymptotes in a rational function: horizontal, vertical, and slant. Horizontal asymptotes are found based on the degrees or highest exponents of the polynomials. If the degree at the bottom is higher than the top, the horizontal asymptote is y=0 or the x-axis. If...

Cyκ controls the level of the horizontal asymptote. If Cyκ = 1, the weighting function (4.66) will approach zero when κ→±∞. This would be the correct value for Cyκ if κ is expected to be used in the entire range from plus to minus infinity. If this is not intended, then ...
If n = m, the horizontal asymptote is y = a/b. If n > m, there is no horizontal asymptote. How many horizontal asymptotes can there be? A function can have at most two different horizontal asymptotes. A graph can approach a horizontal asymptote in many different ways; see Figure 8 in...
