ABSTRACT: This webinar is perfect for those looking to learn the basics about noise and what you can do with it. The main areas covered will include:
- What can I do with noise?
- How is noise created?
- What types of noise can Noisecom provide?
- What do I need to know before purchasing a noise solution?
- Helpful formulas for specific noise parameters
Learn how noise is created, the different types and how to control it. Bob will show how to define your noise requirements so you can identify the specific form factor, including diodes, modules and instruments that provide the best solution for your application.
Webinar Q&A
Below are questions we recieved during the webinar. If you have any additional questions, email us.
Because a simple attenuator at room temperature does not have enough power (Excess Noise Ratio) to be measured by any available instrument and a reversed biased diode circuit can generate sufficient power.
Yes, and FM is currently used by Digital engineers to enhance Random jitter, or white noise in combination. The FM modulated signal is referred to as deterministic jitter in the Total Jitter model defined by PCI sig.
Flat white noise is measured in the frequency domain, and a Gaussian amplitude is measured in the time domain. These are two independent domains, but they are related when speaking about AWGN. A continuous flat white noise band with uniform spectral density usually has a Gaussian amplitude distribution in the time domain provided the amplification chain is not saturated.
Yes the digital generator is more flexible, but better for some applications, typically with narrow band requirements and high power.
- Standard Rule: if the expected noise figure is ≤ 15 dB, the source ENR value should be low, ≤7dB; this is to improve return loss.
- If the expected noise figure is ≥ 15db, then the noise source ENR value ≤ 15 dB over the band.
