Capacitively coupled amplifier

Clean textbook-style black-and-white schematic of a capacitively coupled amplifier stage, with the signal input on the left and output on the right. A two-plate coupling capacitor is placed in series in the input, output, or interstage signal path to indicate capacitive coupling. The amplifier is shown as a rectangular or triangular gain block, optionally with associated resistive elements, straight interconnect lines, node dots, and minimal labels marking the signal path. Simple engineering figure style with clear black circuit symbols and outlines.
