Foundations of Wireless and Electronics [PDF ebook] 

Foundations of Wireless and Electronics, 10th Edition covers the cathode-ray and microwave tubes; modern pulse methods; f.m. detectors; basic processes of transmission; and reception, computers, and non-sinusoidal signal amplification. The book starts by giving a general overview of a complete electronic system, electricity and circuits, capacitance, and inductance. The text also discusses alternating currents (a.c.), including the frequency and phase of a.c.; the capacitance and inductance in a.c. circuits; and the capacitance and inductance in a series. Diodes, triode, transistor equivalent circuits, and a suitable working point are also considered. The book describes oscillation, transmission lines, radiation and antennas, and audio-frequency amplification. The super heterodyne principle, radio- and intermediate-frequency amplification, electronic waveform generators, and switches are also encompassed. The text will be useful to electronics engineers, electricians, and computer engineers.
