{"product_id":"b0h81k8kf7","title":"Amplifier Theory: Tube and Transistor: With a Deep Dive into the Superheterodyne Receiver","description":"\u003cp\u003eFrom a microvolt in the air to music in the room. Amplification is the quiet miracle at the heart of electronics: a whisper of a signal goes in, and a faithful, larger copy comes out.  Amplifier Theory  explains that miracle from first principles — twice. Once through the glowing vacuum tube, once through the cold silicon of the transistor — and then shows them to be two dialects of a single language: a controlled valve with a load line drawn across its curves.\u003c\/p\u003e\n\n\u003cp\u003eStarting with nothing more than the idea of gain, the book builds the decibel, the load line, and the resonant tuned circuit; opens the triode, pentode, and beam-power tube; crosses to the PN junction, the bipolar transistor, and the field-effect devices that run every chip today; and assembles it all into the most elegant machine in everyday electronics — the  superheterodyne receiver  — traced signal by signal from the antenna to the loudspeaker.\u003c\/p\u003e\n\n\u003cp\u003eInside this book 20 chapters across four parts  — plainspoken, but never watered down 87 rendered figures  — device cutaways, load-line constructions, and clean signal-path diagrams Worked examples throughout  — gain, bias, resonance, frequency conversion, and more A full  superheterodyne deep dive : RF front end, mixer, local oscillator and tracking, the IF strip, detection and AGC, and the audio output stage Reference  appendices : formulas, schematic symbols, a decibel table, a receiver-alignment procedure, and typical device parameters Who it’s for Hobbyists and makers, ham-radio and vintage-audio enthusiasts, electronics students, and working technicians who want the  why  beneath the circuits. Whether you hold a soldering iron or just a curiosity about how the signal actually gets bigger, you will close this book able to look inside any amplifier or receiver and understand exactly what you see.\u003c\/p\u003e\n\n\u003cp\u003eCharles Vance writes technical books that make hard subjects clear.\u003c\/p\u003e","brand":"ANT","offers":[{"title":"Ebook","offer_id":67924670382325,"sku":"YSL53618","price":7.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/8774\/8597\/files\/718JqbecqIL._SY1500.jpg?v=1793673484","url":"https:\/\/www.newbooks.store\/products\/b0h81k8kf7","provider":"NewBooks","version":"1.0","type":"link"}
