Introduction: Problemsodern theoretical physics, EM wave is an abstract concept that epitomizes transfer of energy through the space, which is equivalent to say that information is transferred through the space. At the same time, the information itself is embedded into the wave in the form of the energy variation in time

Electrical Resonance: Problems technology, that if by some weird coincidence all LC circuits were dissolved and if we lost the knowledge of its workings, our marvellous electronic technology would have become totally unusable. It is not difficult to imagine consequence of such unfortunate event for our technological civilization

Matching Networks: Problemsnt dividers we learned that the ratio between the signal source impedance and load impedances is extremely important because it directly affects how much the signal amplitude is reduced at the interface node between the source and load. In the ideal case, voltage amplitude stays unchanged if the sou

Sinusoidal Oscillators: Problems intended message. In mathematical terms, a sinusoidal function is required for several key mathematical operations that we meet in the following chapters. Physical embodiment of a sinusoidal waveform is known as an oscillator, whose the only role is to deliver clean predefined either voltage or cur

Signal Demodulation: Problemsextract the carrier envelope. A diode–capacitor based circuit known as . (or, peak detector) is essential part of both AM and FM receivers, as well as many other analog signal processing systems. In this chapter we familiarize with the envelope detector operational principle and operation.
