Waves

Matter waves form the foundation of the theory of quantum physics. French physicist Louis de Broglie was the first one to study this phenomenon. He gave the de Broglie hypothesis in 1924. In his hypothesis he stated that electrons show a wave-like nature. He said that matter has a dual nature. Everything exists as a […]

Modifying the carrier signal in response to the message signal is modulation. In the modulation process, the high-frequency sine wave signal is the carrier signal. The modulating signal is the name given to the output signal. Modulation is a signal processing technique that involves shifting the signal’s frequency range. Modulation is used to enhance the

An amplitude modulated wave is a carrier wave whose amplitude is changed by the parameters of the signal wave or the modulating signal. From the set of many modulation schemes available, amplitude modulation (AM) is an old and very simple modulation technique. In this modulation technique, the information carried by a low frequency modulating signal

Introduction to Amplitude Modulation Amplitude refers to the peak value of any property. For a sigmoid wave, it is the maximum height of the wave.  Modulation is the process of varying the properties of a carrier wave under the signal. Modulation can be of three types. Amplitude modulation occurs when the signal varies the amplitude

Fundamental frequency is defined as the frequency at which a periodic waveform occurs at its lowest point. Each natural frequency produced by an item or instrument has its distinctive vibrational mode or standing wave pattern. These frequencies are referred to as harmonic frequencies, or simply harmonics, in the scientific community. In the presence of a

A wave is a disturbance that travels from one end of a medium to the other. We can observe an ocean wave as it travels across the medium, which is the ocean water. In addition, the crest of the wave may be seen travelling from one site to another over a period of time.  This
