Hello. Can anybody help me with a problem that im having. I have designed a system that has a very low signal to noise ratio. The signal that i am trying to measure is changing very slightly and it is hard to measure due to all the noise that i am getting. The noise is completly random but is...

Can anybody help ive have done some calculations and my capacitance change is going to be in the range of 0.5pf to about 3pf where do i go about getting a wien Bridge oscillator that is affected by this amount of change quite drastically so the frequency ouput changes accoridingly.

Firstly i would like to thank you all for your replies, they are much appreciated. Ok I need the frequency to be altered as much as possible really with only very small adjustments in capacitance. My aim is to produce a capacitance based micro-sensor that can monitor the movements of a human...

Hello. Can anyone help me I have a bit of a proble. My electronics skills are quite limited but I have a grasp of the basics. I want to create a high frequency oscillator circuit in the range of around 10MHz. But I also need to be able to affect the frequency of the oscillator using an...
