Resolution Variable Signal Sampling Apparatus and Method Using FPGA

摘要

Field of the Invention The present invention relates to a variable resolution signal sampling device using an FPGA, and the device according to the present invention is a field programmable gate array (FPGA) and a signal sampling device including a signal delay device, a signal delay control unit, a reference signal generation device, and a data collection unit. It includes. The signal sampling device may receive an external signal synchronized with a reference signal and a data acquisition signal from the FPGA and perform data sampling on the input signal. The reference signal generation device may generate a reference signal and transmit it to the signal delay device, output it as an external output signal, and transmit a delay command signal to the signal delay control unit. The signal delay control unit may transmit a delay command signal transmitted from the reference signal generation device to the signal delay device. The signal delay device may receive a delay command signal transmitted from the signal delay control unit and a reference signal transmitted from the reference signal generation device, and transmit a data acquisition signal delayed by a predetermined amount to the signal sampling device. The n (where n is 0, 1, 2, ... N) data acquisition signal output from the signal delay device may be a signal delayed by m*(n-1)Δt compared to the reference signal. The sampling resolution of the signal sampling device may be 1/(m*Δt).
