we can do analog signal processing also but it is very expensive as comparing with digital signal processing that's why we generally choose the digital signal processing.DSP allows programmable operations.But we cannot do in ASP.
One is analog one is digital
yes
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
please help me to understand the word transducer
AGND means Analog ground & DGND means Digital ground. Due to fast switching of digital signals it is possible for noise generation which affect nearby analog signals.(If common gnd used for both analog & digital). If separate gnd used for both the signals.Noise will not affect the signals.
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.

The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Analog can reach higher speeds.
k,
Analog is displayed in a clock like instrument digital is shoun in numbers
In analog ckt there is more distortion but in digital there is no distortion. Analog is a continues value digital is a discrite value(0 or 1). To measure analog is very difficult but in digital it is very easy. compare to analog the digital system is very compart for us. H.L.Kiran
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
the difference is the "S" and "Z" parameters. S used for analog computation while Z for digital processing. basically Z is the digital approximation of the analog frequency domain signal. Z=exp(sT) where T is the sampling time.
Analog is a clock with the moving hands on it, while digital is computer generated numbers.
Analog signals are continuous while digital signals are discrete
In electrical engineering and computer science, analog image processing is any image processing task conducted on two-dimensional analog signals by analog means (as opposed to digital image processing).
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
