Im wondering if someone could give me some information/resources on ADC's so that i can complete the following questions. I havent got a great deal of knowledge on the subject as i studied it a while back and am recoving it. Any help/ideas would be much appriciated.
1.) A 3-bit successive approximation ADC has a full-scale input of 7V. Explain the steps in the conversion process showing how the 3-bit digital output is arrived at when the analougue input is 5.5V
2.) A 4-bit ADC has a full-scale input of 10.5V. What is the 4-bit binary output when the input is 4.0V?
3.) An ADC has a conversion time of 1us. It is used t sample and digitally store frequencies of up to 50kHz. how many samples is this ADC able to do one complete cycle of 50kHz?
4.) A microphone is used to record music. The maximum output voltage over the whle performance is 300mV. the music i to be digitised and stored using an ADC with a full-scale input of 2.5V. What voltage amplification is required between microphone output and ADC input?
