Classification of Signals HAO TO Introduction to Digital Signal Processing--Review for Signal and System A continuous-time signal with a continuous amplitude is usually called an analog signal A discrete-time signal with discrete- valued amplitudes represented by a finite number of digits is referred to as the digital signal A discrete-time signal with continuous valued amplitudes is called a sampled- data signal A digital signal is thus a quantized sample data signal 上浒充通大
