T] Nyquist traces to analyze the circuit) allows to get some very useful parameters as gain margin
, loaded quality factor ([Q.
1997), some robustness measures like gain margin
, modulus margin can be calculated.
At the same time, rising production and transportation costs are forcing some national brand manufacturers to downsize their products, in an attempt to gain margin
Once the linear oscillation criteria are established for the open-loop cascade, the loop is closed, and the oscillation level builds until the device nonlinearity absorbs the excess gain margin
at the phase-zero crossing frequency.
, the amount the gain has fallen below unity when the total phase lag is 360[degrees], is expressed in decibels.
Most mass merchants commonly use big-title new releases as loss leaders, so they must rely on other titles--like direct-to-video--to gain margin
The Bode phase diagram is superimposed on the magnitude plot for easy calculation of phase margin or gain margin
On the other hand, the linear simulation can only estimate the oscillation frequency, gain margin
and oscillator [Q.
A common rule of thumb is to begin the design with a 45 [degrees] phase margin at 0 dB gain margin
