Practical Circuits
Each group below is a real teaching page, not just a topic list. Read the explanation, use the checklist to make sure the main ideas are sticking, then quiz that group if you want an immediate check.
G7A
Power Supplies & Schematic Symbols
A power supply converts available energy into stable DC voltages a radio can use. The schematic shows that conversion as a chain of functional stages.
Study G7A →G7BDigital Circuits, Amplifiers & Oscillators
Digital circuits make logic decisions, amplifiers increase signal level, and oscillators generate repeating signals. Those three jobs appear throughout modern radios.
Study G7B →G7CTransceiver Blocks, Filters & DSP
A transceiver is a chain of blocks that select, convert, amplify, and process signals. Following the signal path is more useful than memorizing one radio model.
