No and yes. Digital signals are usually square or pulse waves. By Fourier analysis, however, every periodic wave, even a square wave, is the summation of some series (often infinite) of sine waves.
An analog signal has a sine wave form and a binary signal has a block "wave" form. The binary signal is either on or off ("up" or "down"), and never anything in between. analog: http://img99.imageshack.us/img99/7723sineuk6.jpg binary: http://img154.imageshack.us/img154/1894binarypb6.png

Digital television is simply the process of broadcasting a digital signal, instead of an analog one. This results in better sound and picture quality, as well as increased coverage.
As a sinusoidal signal is clipped the waveform approaches a square wave.
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
A digital wave is typically represented as a series of values plotted over time on a graph. It can take the form of a series of discrete values or a continuous waveform, depending on the nature of the digital signal being represented. Visual representations of digital waves can vary depending on the software or tool used to generate them.
A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
What one needs is a bit of hardware circuitry called a Analogue to Digital Converter (ADC). These work by sampling the analogue electrical waveform.
Form factor of an alternating current waveform (signal) is the ratio of the RMS (Root Mean Square) value to the Absolute Average Value (also referred to as the Practical Average Value) of the waveform.In the case of a sinusoidal wave ie., an analogue wave, the form factor is approximately 1.11.In the case of a square wave ie., a digital wave, the RMS and the average values are equal; therefore, the form factor is 1.
Transverse waves exist in both digital and analog forms. The nature of the wave itself (transverse) is independent of whether the signal it carries is digital or analog. The modulation or encoding of the wave determines whether it is digital or analog.
The three basic characteristics of a wave are amplitude (height of the wave), wavelength (distance between two peaks of the wave), and frequency (number of complete oscillations of the wave per unit of time).
Yes, it is
It's usually analog, but digital signals can be converted, if needed.
no light is a wave Analog are waves Digital is pulses (1 or 0)
digital generator nothing but square wave generator or astable multivibrator
