Frequency response is defined as: A measure of the effectiveness with which a circuit, device, or system transmits the different frequencies applied to it. It is a phasor whose magnitude is the ratio ...

Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

When sound is represented by an electrical signal, it can be changed in many ways. Audio devices (such as mixing consoles and tape recorders) and entire audio systems can make useful changes to the ...

Frequency response measurements are a mainstay of RF communications design and generally considered a routine task—unless one of the device ports happens to be at I-Q baseband. Here, the convenience ...

High-speed photodetectors are vital components in modern optoelectronic systems, especially in enabling ultrafast data transmission and next-generation integrated circuits. The characterisation of ...

[Hans] wanted to see the frequency response of a bandpass filter but didn’t have a lot of test equipment. Using an RTL-SDR dongle, some software and a quickly made noise generator, he still managed to ...

Software-defined radio (SDR) is a very powerful concept. Its technologies provide software implementation of modulation, interference management, and capacity enhancement techniques over a broad ...

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...
