[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video ...

Modulation Measuring the quality of the modulation is important for making sure a system is working properly and that the information is being transmitted correctly. Understanding the spectral content ...

[Camilo] built a spectrum analyzer to use with his audio system (translate). The hardware is quite simple, using an op-amp, microcontroller and LCD display. He chose an LMV324M low-voltage op-amp ...

The analysis of electrical signals, otherwise known as signal analysis, is a fundamental challenge for virtually all electronic design engineers and scientists. While it provides valuable insight into ...

Noise from the power supply, linear regulators, and voltage references is a major contributor to the limitations of system performance, especially in instrumentation and communications products. In ...

Audio Precision has introduced its new APx555 B Series analyzer. According to AP, the second-generation APx555 offers improved sine generator frequency stability, lower system residual distortion, ...

A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

Technological innovation in RF continues to advance relentlessly, due in large part to sustained growth in the military and communications sectors. Commercial communications networks and modern radar ...

Today’s RF test instruments are highly complex products and are therefore characterized by a wide variety of specifications. We have presented a three-part series on a wide array of RF instrument ...
