Advantages
The advantage of direct coupling is very good low frequency response, often from DC (if the input/output coupling capacitors are not used) to the highest operating frequency that the system will allow. Most industrial applications that require monitoring of slowly changing signals (such as those from thermistors, thermocouples, etc.) must have a very good DC amplification with minimum offset errors and hence they have to be directly coupled throughout by default, and have offset correction or trimming incorporated into them.

Famous quotes containing the word advantages:
“The advantages found in history seem to be of three kinds, as it amuses the fancy, as it improves the understanding, and as it strengthens virtue.”
—David Hume (1711–1776)
“A woman might claim to retain some of the child’s faculties, although very limited and defused, simply because she has not been encouraged to learn methods of thought and develop a disciplined mind. As long as education remains largely induction ignorance will retain these advantages over learning and it is time that women impudently put them to work.”
—Germaine Greer (b. 1939)
“There are great advantages to seeing yourself as an accident created by amateur parents as they practiced. You then have been left in an imperfect state and the rest is up to you. Only the most pitifully inept child requires perfection from parents.”
—Frank Pittman (20th century)
