noun
cascade connection
Technical term in electronics for connecting circuits or devices in series, where the output of one feeds into the input of the next.
増幅回路を縦続接続して利得を高める。
Amplifier circuits are connected in cascade to increase the gain.
直列接続 is a more general term for series connection, while 縦続接続 specifically refers to cascade connection in electronics, often with signal flow from one stage to the next.
Compound of 縦続 (cascade, series) and 接続 (connection). The exact historical derivation is uncertain; the spelling is conventionally associated with the technical meaning.
