*Description:*
This video by HP Study covers the concept of *multistage amplifiers* in analog circuits, particularly relevant for AKTU, B.Tech, and GATE preparation. It explains why single-stage amplifiers are often insufficient and details the purpose and design of multistage amplifiers, types of coupling devices (resistor, capacitor, transformer), and the concept of cascading stages for improved gain and performance. The lecture also analyzes how multistage design affects frequency response, including lower and higher cutoff frequencies, and demonstrates related calculations with step-by-step examples in Hindi. Other topics like oscillator types are mentioned, and viewers are guided to relevant playlists for further study[1].
