Note that: step size = Δ = (xmax − xmin)/(23 − 1); xmax = maximum voltage; and xmin = −xmax; and coding format: (a) sign bit: 1 = plus; 0 = minus; (b) 2 magnitude bits. The following example serves to illustrate coding principles of the 3-bit midtread quantizer.

What is meant by quantization step size?
Definition: the quantization step size is the smallest possible difference in amplitude. between samples. Definition: the sampling interval is the difference in time between successive samples. The resulting digital data is thus both temporally discrete and amplitude discrete.
How do you calculate step size in PCM?
For uniform quantizer, the step size is given by: Δ = V p − p L ; L = 2 n = number of encoding levels and n is the number of bits required to represent the given encoding levels.
What is the step size of?
Step Size. The step size is the voltage difference between one digital level (i.e. 0001) and the next one (i.e. 0010 or 0000). For example if an ADC has a step size of 1 Volt an input of 1 volt will produce an output, in a 4 bit converter, of 0001. 0 volts is always considered 0000.
