Administrative controls can be broken down into two categories; programs such as HAZCOM and activities such as housekeeping is a TRUE statement.
Explanation:
- Administrative controls (or work practice controls) are changes in work procedures such as written safety policies, rules, supervision, schedules, and training with the goal of reducing the duration, frequency, and severity of exposure to hazardous chemicals or situations.
- Some common examples of administrative controls include work practice controls such as prohibiting mouth pipetting and recapping of needles, as well as rotating worker shifts in coal mines to prevent hearing loss.
- Administrative controls are fourth in larger hierarchy of hazard controls, which ranks the effectiveness and efficiency of hazard controls.
- The two categories of administrative controls programs and activities.
Answer:
Using Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common-carrier frequency.
Explanation:
- In SSB modulators, we pre-process a real signal by Hilbert Transform filter to form another real signal
- The signal has the same spectral amplitude but has 90° phase shift at each frequency relative to its input signal.
- The ordered pair gets almost all of its negative components cancelled
- thus, with the use of Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common carrier frequency.
