In electronics and telecommunications, pulse shaping is the process of changing a transmitted pulses' waveform to optimize the signal for its intended purpose or the communication channel. This is often done by limiting the bandwidth of the transmission and filtering the pulses to control intersymbol interference .

The Chain Bridge (German: Kettensteg) is a pedestrian chain bridge in Nuremberg, Germany. The bridge crosses the river Pegnitz just a few meters upriver of Fronveste and Schlayerturm, fortifications in the course of the medieval city wall guarding the river's exit from the town. It connects Maxplatz in Sebalder Altstadt (the old quarter north ...
The Széchenyi Chain Bridge (Hungarian: Széchenyi lánchíd [ˈseːt͡ʃeːɲi ˈlaːnt͡shiːd]) is a chain bridge that spans the River Danube between Buda and Pest, the western and eastern sides of Budapest, the capital of Hungary.
Examples of pulse shapes: (a) rectangular pulse, (b) cosine squared (raised cosine) pulse, (c) Dirac pulse, (d) sinc pulse, (e) Gaussian pulse. A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. [1]

In addition to the DC input, the circuit requires a feed of two clock pulse trains with an amplitude swinging between the DC supply rails. These pulse trains are in antiphase. [1] The Dickson multiplier is intended for low-voltage applications, unlike Greinacher/Cockcroft–Walton which is commonly used in high-voltage applications. This is ...
A frequency comb or spectral comb is a spectrum made of discrete and regularly spaced spectral lines.In optics, a frequency comb can be generated by certain laser sources.. A number of mechanisms exist for obtaining an optical frequency comb, including periodic modulation (in amplitude and/or phase) of a continuous-wave laser, four-wave mixing in nonlinear media, or stabilization of the pulse ...
