The circuit has been designed to develop a speech filter that will improve the signal processing circuit for optimizing speech recognition. TL072 – a low noise JFET input operational amplifier with ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

Listen to the pop, sizzle, and hum. Look at the bars and wavy lines. These and other characteristics of electromagnetic interference (EMI) are very familiar. RF energy is radiated from a culprit ...

Circuit VR is where we talk about a circuit and examine how it works in simulation with LT Spice. This time we are looking at a common low-frequency oscillator known as the Wien bridge oscillator.

As a follow-up to my previous blog, Integration Choices: Analog Filters vs. Digital Filters, the next step would be to discuss how to integrate filters into the IC itself. What techniques and ...

Protecting single-phase power circuits is the job of a combination surge protector and EMI/RFI filter device. The Trabtech surge filter includes a coordinated TVSS and EMI/RFI filter circuit, ...
