Spectrogram | Spectrogram ( waterfall display ) of an Olivia 16 / 500 signal centered on 7073. 25kHz

The Spectrogram produced by such an instrument is a graphical display of the time varying pressure level and frequency profiles which give a specific acoustic signal its defining character.

Spectrogram of a Linear Chirp.

The Spectrogram plot demonstrates the linear rate of change in frequency as a function of time, in this case from 0 to 7 kHz repeating every 2. 3 seconds.

Spectrogram of an exponential chirp.

Also visible in this Spectrogram is a frequency fallback to 6 kHz after peaking, likely an artifact of the specific method employed to generate the waveform.

Spectrogram illustrating the difference between tremolo and vibrato.

The first part of the road was steep, but it leveled off after the second bend and curled gradually into the valley.

For men who had left cattle alone after getting their first notices had received no second.

He had received both first and second anonymous notices, and each time he had accused his neighbors of writing them.

John Adams fashioned much of pre-Revolutionary radical ideology, wrote the constitution of his home state of Massachusetts, negotiated, with Franklin and Jay, the peace with Britain and served as our first Vice President and our second President.

The active sponsor of Jefferson's measure for religious liberty in Virginia, Madison played the most influential single role in the drafting of the Constitution and in securing its ratification in Virginia, founded the first political party in American history, and, as Jefferson's Secretary of State and his successor in the Presidency, guided the nation through the troubled years of our second war with Britain.

The first half of The Charles Men, ending on the climax of the battle of Poltava in 1709, is more dramatically coherent than the second.

Even to be `` from hope and fear set free '' is at least better than to have lost the first without having got rid of the second.

The House was his habitat and there he flourished, first as a young representative, then as a forceful committee chairman, and finally in the post for which he seemed intended from birth, Speaker of the House, and second most powerful man in Washington.

Obviously, if this club is going to move from second to first in the American League, it will have to show improvement someplace.

So, all in all, the infield can't be expected to supply the added improvement to propel the Birds from second to first.

When this second dilemma first became obvious -- during the mid to late '50's -- the United States appeared to have three choices.

As it has turned out, however, the excessive enthusiasm in the first instance and the loss of hope in the second were both wrong responses.

The ledger was full of most precise information: date of laying, length of incubation period, number of chick reaching the first week, second week, fifth week, weight of hen, size of rooster's wattles and so on, all scrawled out in a hand that looked more Chinese than English, the most jagged and sprawling Alex had ever seen.

Since accurate base maps are necessary for any planning program, the first step taken by the planning division to implement the long-range state plan has been to prepare two series of base maps -- one at a scale of 1 inch to a mile, and the second a series of 26 sheets at a scale of 1 inch to 2000 feet, covering the entire state.

He is interested in public opinion for two reasons: first, because it is important in itself, and, second, because he knows that the American public cares about a decent respect for the opinions of mankind.

If the plants are cared for and protected over the winter, the second year is more prolific than the first.

In many cases the revolutionary production has offered no more than sensational effects: the first hearing was fascinating and the second disillusioning as the gap between sound and substance became clearer.

The second piece is in turn glued and screwed to the first.

In a two-story house, one unit may be installed in the basement to serve the first floor, another in the attic to cool the second.

The expectation is that first-level supervisors will be selected in approximately equal numbers from the second and third engineering level, with very few coming from the first level.

When 1 ml of conjugate was passed through a column ( Af ), the first and second milliliter fractions collected were the most specific and gave no nonspecific staining in some experiments, and very little in others.

In our work the best procedure for removing substances causing nonspecific staining in order to obtain specific conjugates was to pass the conjugates through a DEAE-cellulose column and in some cases to absorb the first and second milliliter fractions with sweet clover tissue powder.

The word `` binomial '' means `` of two names '' or `` of two terms '', and both usages apply in our work: the first to the names of the two outcomes of a binomial trial, and the second to the terms P and Af that represent the probabilities of `` success '' and `` failure ''.

Continuing with the case in which **zg is a Af curve on a quadric Q, we first observe that the second regulus of Q consists precisely of the lines which join the two free intersections of **zg and the planes through any one of the multiple secants.

This subject was one who gave an arm-elevation on the second trial in the naive state but not in the first.

But under standard rules, black would have to first remove the F8 / G10 link in order to place F9 / H8, and that would allow white to then play at E9, double linking to D11 and G8.

These are Gaia ( climbing grade E8 6b ), up the groove in the massive nose that one sees first on the walk to the top, and Meshuga ( grade E9 6c ), on the main overhanging Promontory.

In 1986 he introduced the grade E9 to the British grading system with a first ascent of the route " Indian Face " on the Welsh crag Clogwyn Du ' r Arddu, about which he wrote:

The first of the E9 coupés, the 2800CS, replaced the 2000C and 2000CS in 1968.

One of the first tests of HEP powered by an EMD locomotive's prime mover was in 1969, on Milwaukee Road EMD E9 # 33C, which was converted to have a constant speed rear engine.
