When multistage designs are intended using low power op amps, the load presented by a poorly designed stage might in fact impair the intended signal frequency response above the high pass corner. Some ...

Today we are going to explain about one more important concept – “FILTERS”. An electrical filter is a circuit, designed to reject all unwanted frequency components of an electrical signal and allows ...

Today I am experimenting with a single chip Universal Active Filter, in this case I made a small PCB for the UAF-42 from Texas Instruments. I chose this part in particular as it facilitates setting ...
