MANUALE COMPLETO DI JAVA

devo dire che la sintassi di Java è molto simile, anzi quasi uguale a quella del C, mentre per chi non conosce il C, le parentesi graffe rappresentano il begin e l'end del pascal. La classe avrà un cosiddetto costruttore (o più di uno), che è un metodo particolare che di solito viene utilizzato per inizializzare gli attributi quando viene

Analog Transmission of Digital Data: ASK, FSK, PSK, QAM

Modulation of Digital Data: FSK 8 FSK – frequency of carrier signal is varied to represent binary 1 or 0 • peak amplitude & phase remain constant during each bit interval • demodulation: demodulator must be able to determine which of two possible frequencies is present at a given time • advantage: FSK is less susceptible to errors than ASK – receiver

CD4046B Phase-Locked Loop: A Versatile Building Block for ...

Applications of the CD4046B phase-locked loop device, such as FM demodulation, FSK demodulation, tone decoding, frequency multiplication, signal conditioning, clock synchronization, and frequency synthesis, are discussed. The monolithic-form low-power-consumption CD4046B particularly is desirable for use in portable battery-powered equipment ...
