hi i was wondering if anyone could tell me about a sigma-delta convertor
what its general functions and the advantages/disadvantages over other ADC's?
thanks
hi i was wondering if anyone could tell me of any good dc peak detection circuits. the voltages i am measuring are varying by one hundredth of a volt.
i have been using the peak detector on the wqikipedia website but the circuit doesn't seem to store the peak voltage as the reading on the dmm...
i could but i was needing to use a peak detector to store the peak voltage and have that value stored by a computer program
and i know this sounds lazy but the DC peak detector circuit looked much easier to construct on a protoboard than a AC peak detector
thanks for your help
heres what I've got so far,
ive got one connection of a signal generator (100KHz) connected to a coil (electromagnet) which is connected in series with a 1 ohm resistor which is connected back to the signal generator. I've been measuring the voltage change across the resistor when different...
hi, as part of a project me and my friends are undertaking we are trying to measure the change in resistance of an electromagnet when a coin is placed near near the electromagnet. i have been trying to use a bridge rectifier to convert the system to DC but i have been encountering a few...
