Analog signals are continuous in nature, whereas digital signals are discrete. Type of Waves Analog signal wave type is sinusoidal, whereas a digital signal is a square wave. Medium of Transmission Analog signal medium of transmission is wire or wireless, whereas a digital signal is a wire. Typ...
Broadband (random) signals: Autopower spectra withdifferentfrequency resolutions will havedifferentamplitude levels. Power Spectral Densities withdifferentfrequency resolutions will have thesameamplitude levels. Sinusoidal (periodic) signals: Autopower spectra withdifferentfrequency resolutions will have thesameampl...
A Lissajous figure is displayed on thescreen when sinusoidal signals are applied to both horizontal & vertical deflection plates of CRO. Hence, apply the sinusoidal signals, which have same amplitude and frequency to both horizontal and vertical deflection plates of CRO. Lissajous figures demonstrated ...

A continuous-time signal xa(t) is composed of a linear combination of sinusoidal signals of frequencies 300Hz, 500Hz, 1.2kHz, 2.15kHz and 3.5 kHz. The signal xa(t) is sampled at a 3 kHz rate, and the sampled sequence is then passed through an ideal lowpass filter with a cutoff frequ...
Here the input signals (V1and V2) are applied to the base of the transistors while the output is collected across their collector terminals (Vo1and Vo2). The circuit diagram for a BJT differential amplifier is shown below: In this case, if the V1at Q1is sinusoidal, then as V1goes on...
The delayed line-type SAW sensor receives a sinusoidal excitation signal through an antenna and is transmitted to the interdigital transducer, IDT. The sinusoidal signal is excited on the piezoelectric substrate, and the conversion of acoustic waves and electrical signals is realized. The sound surfa...
A sinusoidal signal, in the continuous realm can be expressed in the following form: Where the subscript ‘a’ denotes the analog nature, F is the frequency and t is continuous time. Now let us create or synthesize digital sinusoidal signals. So the first thing we need to do is generate ...
The self-induced e.m.f.s is directly proportional to the rate of change of the current through the inductor and it is greatest when the supply voltage crosses over from its positive half cycle to negative half cycle or vice versa along with the AC sinusoidal wave. Do Inductors Have Polarit...
An electrical device known as an oscillator generates a periodic signal at a predetermined frequency, often a sinusoidal signal. They are a typical component in many contemporary devices. If you wish to generate a signal at a specific frequency, you need an oscillator. Oscillators are widely used...
