Difference Between AC & DC Amplifiers
If you've been trying recently to get a deeper understanding of power amplifiers, you have probably come across terms AC amplifier and DC amplifier. What was your first thought? Was it Alternating Current and Direct Current? Well, terms AC and DC in amplifiers don't exactly refer to current. These terms refer to the coupling method between different stages of amplification.
Our article is designed to help you understand the working principles of each of these two amplifier types, and explain the differences between AC and DC amplifiers.
What is The Meaning of AC and DC in AC/DC Amplifiers?
AC in AC amplifiers tells us that different stages of amplification are coupled with a capacitor or a transformer. These capacitors/transformers are, therefore, known as coupling capacitors/tr...
