Noel Maginnity is a consultant in Carterton, New Zealand. An alternative audio program input is often required at a medium-wave transmission site. During STL maintenance or if the STL fails, it is ...

This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and ...

Analog signal processing has conventionally been viewed as a voltage-dominated form of design. But voltage-mode processing can restrict the system's dynamic range. There is also a limitation on the ...

How an electro-optic PIC can implement RF filtering functions. Which E-O components are needed for passband and notch filtering. How the overall device was fabricated and the test results. It’s a very ...
