To fix this, a sub-wire harness (filter) will be installed to minimise electrical noise from the other electrical components," said Williams.
Amplifiers designed for old analogue reception often generate considerable electrical noise, which is bad news for digital signals, so would need replacing with amplifiers designed for the digital age.
Shielded from extreme conditions in temperature, contaminants, moisture, vibration, and radiated or emitted electrical noise, ruggedized enclosures ensure that critical computing applications operate reliably, with minimum repairs and downtime.
In addition, neither the motor nor the control circuit should emit electrical noise that might disturb other electronic components, and they must be hardened so that they experience no deterioration if they are subjected to electrical noise spikes from other sources.
Optional EMI/RFI filtering protects connected equipment from electrical noise.
This is "quite a feat," the company comments, considering that "MSD ignition coils for high-powered racing cars can generate up to 50,000 volts of electrical potential in repeated bursts, producing intense electrical noise.
Electrical noise and interference was also a problem with early trials, but the HomePlug Alliance claims to have overcome this obstacle.
While a variable frequency drive VSD can be retrofitted to a standard compressor, it will produce electrical noise.
Because the pacemaker measures minute electrical signals from the heart, there is the potential that stray electrical noise in the environment could interfere with the pacemaker's normal function.
Their Sonic Intelligence signal-processing software is said to differentiate between true echoes from the material and false echoes generated by obstructions or electrical noise.
