A mi me interesa el medidor de distorsión y el Designing low noise audio amplifiers, falta ver el resto que no es poquito....

Yo me empaché chusmeando los receptores conversión directa, estoy por hacer uno y encontré referencias.
¡Gracias por subir la información!

Las 2 últimas "Adquisiciones" de la FogoBiblioteca

Critical dumping (Pearl Perkins Electro-Acoustic Research Laboratory)
Dumping Factor (Ka Nang Leung, Philip K. T. Mok, Wing-Hung Ki, Johnny K. O. Sin IEEE)
Tomé prestado un articulo sobre un microfono espía (esto lo digo porque parece preocuparte haberlos subido para nada) y le fabriqué un pcb pero todavia no lo probé.
Tambien estube leyendo "Baxandall tone control revisited DCD" que hace dias estoy tratando de modificar el triple tono de tupolev (no hacerle mejoras, solo probar para conocer) y esto me llevó a esto: y la cosa se puso negra con mi pobre ingles y mi malas matematicas pero bue.
Tambien tome el "Simon" pero el chip... es carito. Y claro que hay muchas cosas interesantes pero voy despacito.
A proposito para calcular tonos existe un programa "Tone stack Calculator" que ayuda bastante.
Gracias por tanto Fogonazo.
