+ | In this course sqrt(-1) is banned! We do not know how to derivate/ | ||
+ | |||
+ | This first lesson covers all components except the most difficult one, the transmission line. It is covered in the antenna lesson. | ||

+ | * Ohms Law. U = RI, P=UI, thermal efficiency (mu). | ||
+ | * Resistors (R) | ||
+ | * get hot | ||
+ | * P = RI^2 = U^2/R | ||
+ | * potentiometers | ||
+ | * Decibel: x dB = 10 log (power level / reference power level) | ||
+ | * AC/ | ||
+ | * Capacitors (C) | ||
+ | * Z = 1/ | ||
+ | * Energy stored = C *V^2/2 | ||
+ | * Bleeder resistors | ||
+ | * Polarization | ||
+ | * Inductors (L) | ||
+ | * Z=2*pi*f*L | ||
+ | * Energy stored = L*I^2/2 | ||
+ | * Use two-pole switches | ||
+ | * Transformers | ||
+ | * Memristors are ignored | ||
+ | * Series and parallel connections of R/L/C | ||
+ | * Time domain and frequency domain -> filters | ||
+ | * Low pass RC or LC | ||
+ | * High pass CR or CL | ||
+ | * Band pass (L+C) | ||
+ | * Band stop (L+C) | ||
+ | * All-pass!? | ||
+ | * Resonance | ||
+ | * parallel resonance | ||
+ | * Series resonance | ||
+ | * Q | ||
+ | * Crystals | ||
+ | * Electron tubes | ||
+ | * Diode | ||
+ | * Triode | ||
+ | * Semiconductors | ||
+ | * Diode | ||
+ | * Zener diode | ||
+ | * Bipolar transistor, PNP, NPN, current gain | ||
+ | * MOSFET transistor, n-channel, p-channel. | ||
+ | * Rectification | ||
+ | * u_peak_DC = u_rms_AC*sqrt(2) = u_peak_AC | ||
