WebIn this video the operation of Tri-state buffer (Controlled buffer) is discussed. WebThe men in white coats refer to this circuit as a cathode follower stage but it’s also commonly known as a ‘buffer’. This is because the circuit has high input impedance and low output impedance meaning it can effectively isolate or buffer one part of an audio circuit from another to prevent loading.

WebOct 7, 2024 · A buffer is an aqueous solution that has a highly stable pH. A buffering agent is a weak acid or weak base that helps maintain the pH of an aqueous solution after adding another acid or base. If you add an acid or a base to a buffered solution, its pH will not change significantly. WebFundamentally, a buffer is an amplifier. It takes a small signal (lightly loading the source of the signal) and provides a copy of that signal that can drive a heavy (e.g., capacitive) …
