(a) (i) (ii) input 1 R₁ (a) (b) (c) (d) (e) 4.7 ΚΩ output Figure 2.1 Figure 2.1 shows a circuit for an inverting amplifier using a silicon transistor. With the aid of a diagram explain what is meant by an inverting amplifier. 10 V The transistor has a current gain of 80. With no input signal applied to the amplifier, the DC voltage between the collector and emitter of the transistor is 5 V. Calculate: the voltage across the collector resistor the collector current the base current the emitter current the resistor R₁
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.
