In RF communication, pulse shaping is essential for making the signal fit in its frequency band. Typically pulse shaping occurs after line coding and before modulation . Need for pulse shaping Transmitting a signal at high modulation rate through a band limited channel can create intersymbol interference . As the modulation rate increases, the signal s bandwidth increases. When the signal s bandwidth becomes larger than the channel bandwidth, the channel starts to introduce distortion to the signal. This distortion is usually seen as intersymbol interference. The signal s spectrum is determined by the pulse shaping filter used by the transmitter.

unreferenced date October 2010 In digital signalprocessing , the normalized frequency of a periodic signal is its frequency expressed in units of cycles or radians per Sampling signalprocessing sample , rather than in the usual International System of Units SI Units of measurement units of hertz cycle per second cycles per second . The cycles per sample frequency is computed by dividing the cycles per second frequency by the sampling rate samples per second symbolically, the second per second units cancel cycles second samples second cycles sample. Applications The abstract reason for using normalized frequency is that, from the point of view of signalprocessing, a second is an arbitrary unit of time, while the sampling interval is a meaningful quantity formally, a characteristic unit for the system the frequency of a signal with respect to 1 second does not tell you about the behavior of the signal, but the frequency of a signal with respect to the sampling interval tells you the effect of sampling on the signal, via the sampling theorem . Stated alternatively, this process is called normalization , and the sampling frequency is a normalizing constant . In filter design , a given design can be used at different sample rates, resulting in different frequency responses. Normalization produces a distribution that is independent of the sample rate, and thus one plot is sufficient for all possible sample rates. Alternative normalizations The reference value is usually the sampling frequency, denoted math f s, , math in samples per second , because the frequency spectrum of a sampled signal with real number real or complex number complex values is periodic with period ...

Multirate signalprocessing techniques are necessary for systems with different input and output sample rates, but may also be used to implement systems with equal input and output rates.

It is a term common to Analog synthesizer synthesizer programming, and is a typical waveform available on many synths. The exact shape of the wave is determined by the duty cycle of the oscillator .
