10. Signals
Signal source
Transducers are the devices which can convert the non-electric signal to electric signal, or vice versa. Signal source is the transducer witch can produce electric signal.
Representation of the signal source
Thévenin form
Norton form
SJTU Zhou Lingling

11. Representation of the Signal Source
Two alternative representations of a signal source:
(a) the Thévenin form
(b) the Norton form

12. Time-Domain Representation of Signal
An arbitrary voltage signal vs(t).
SJTU Zhou Lingling

13. Time-Domain Representation of Signal
Sine-wave voltage signal of amplitude Va and frequency f = 1/T Hz. The angular frequency ω = 2πf rad/s.
SJTU Zhou Lingling

14. Time-Domain Representation of Signal
A symmetrical square-wave signal of amplitude V.
SJTU Zhou Lingling

15. Frequency-Domain Representation of Signal
The frequency spectrum of an arbitrary waveform is continuous function of frequency. It means the spectrum contains all possible frequencies.
SJTU Zhou Lingling

16. Frequency-Domain Representation of Signal
The frequency spectrum of the periodic square wave consists of discrete frequencies.

17. Analog and Digital Signals
Analog signal
The magnitude of analog signal can take on any value and exhibits a continuous variation over its range of activity.
Digital signal
The representation of digital signal is that of a sequence of numbers, each number only have two possible value:low and high.
SJTU Zhou Lingling

18. Analog and Digital Signals
Sampling
Sampling the magnitude of an analog signal at discrete instants of time and representing each signal sample by a number results in a digital signal.
ADC and DAC

19. Sampling Sampling the continuous-time analog signal in (a)
Results in the discrete-time signal in (b).

21. Amplifier
A voltage amplifier fed with a signal vI(t) and connected to a load resistance RL.
SJTU Zhou Lingling

22. Amplifier
Transfer characteristic of a linear voltage amplifier with voltage gain Av.
The straight line means the amplifier is a linear amplifier.
SJTU Zhou Lingling

23. Amplifier
An amplifier transfer characteristic that is linear except for output saturation.
Output waveform is clipped off.
Nonlinear distortion exists.
