In PCM encoding, quantization level varies as a function of ________(a

1.	In PCM encoding, quantization level varies as a function of ________(a) Frequency(b) Amplitude(c) Square of frequency(d) Square of amplitudeThis question was posed to me in an interview for job.Enquiry is from Pulse Code Modulation in portion Formatting and Baseband Modulation of Digital Communications
Answer» Right CHOICE is (b) Amplitude For explanation I would say: In linear PCM the quantization levels are uniform. But in normal PCM ENCODING the quantization level vary according to the amplitude, BASED of A-law of Myu-law.
