Furthermore, analog signals can be defined by two ways –using amplitude and time period or using frequency and phase.To analyse the greatest height of the signal, amplitude is used. Frequency measures the rate of change of the analog signal. Phase specifies the position of the signal with re...
In this book, an introduction to discrete linear systems and digital signal processing is given. This book is primarily intended for undergraduates in electrical and computer engineering to master this subject and to apply MATLAB for solving typical problems in this field. It contains many solved pr...

Analog and digital signalsare different types which are mainly used to carry the data from one apparatus to another. Analogsignals are continuouswave signals that change with time period whereas digital is a discrete signal is a nature. The main difference betweenanalog and digitalsignals is, analo...
Infrequency shift keying, when the immediate frequency of the carrier signal is changed then the information will be transmitted. In this type of modulation, carrier signal has two pre-defined frequencies namely wc1, and wc2. Whenever the data bit is ‘1’ then the carrier signal by wc1 is...
The definition of the discrete STFT of a digital signal is as following:,(-window function,-length of )。Please explain the above discrete STFT from filtering point and demonstrate the OLA method of the inverse discrete STFT(即证明离散STFT反变换的OLA法,有时又称着OLA综合方法)。
Digital data transmission is the transmission of discrete data using two distinct electric states. A ‘1’ for “on” and ‘0’ for “off” represents these two states. The transition between the values of a digital signal is instantaneous, like a light that turns on and off. Digita...
Digital modulation is the process of encoding a digital information signal into the amplitude, phase, or frequency of the transmitted signal. This encoding affects the bandwidth of the signal and its ability to withstand channel impairments.
