DSP Quantisation
An analogue signal is to be sampled from a transducer with an output voltage range of 0 to 10 volts and operating on a 12-volt power supply. The designer has available two analogue to digital converters (ADC): a 3 bit ADC and a 4 bit ADC. For each converter:
(a) Supply the quantisation levels (including zero) that are available. Do this for both the three and 4-bit ADC in table form.
(b) What is the resolution of each quantizer?
(c) What is the maximum quantisation error?
Frequency Range, Local Oscillator Frequency, Image Frequency, and Attenuation, A radio receiver for the AM broadcast band covers the frequency range 550 to 1600 kHz. The IF frequency is 455 kHz and the local oscillator is above the received signal..
