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. Pulse shaping is particularly important in RF communication for fitting the signal within a certain frequency band and is typically applied after line coding and modulation.

WebBy filtering BPSK modulation, the spurious emissions are reduced, enabling up to 8 independent transmit channels in the U.S. ISM band. Inputs are provided for spread-spectrum BPSK, ASK, and OOK. FM can be achieved by directly modulating the VCO. The device is intended primarily for use with external differential antenna. WebIn this paper, RC filters are eliminated by the pulse amplitude modulation (PAM) BLDC drive. Besides, the diode commutation reflected voltage spike can be compensated based on the flux estimation with phase voltage integration. This filter free flux-based sensorless BLDC drive directly measures phase voltages for position estimation.
