Abstract

PURPOSE:To expand definitely an output waveform of a radio receiver by allowing a narrow-band sweep part to follow up a marker even if moved to any position. CONSTITUTION:Direct-current voltage (5), obtained by sampling and holding a linear saw-tooth wave by marker pulse (2) in sample holding gate circuit 5, is compared 7 with linear saw-tooth wave (6) which is equal in rising gradient to saw-tooth wave (1) and increased in bias potential by bias offset circuit 6 to generate pulse wave (7) whose leading edge is before pulse (2). Leading edge X of pulse wave (7) is differentiated by pulse comparator 8 to generate pulse (8). Pulse (8) is applied to monostable multivibrator 9 to generate pulse signal (9) whose leading edge Y is positioned before a marker pulse while trailing edge Y' is behind the marker pulse. Signal (9) and synchronizing pulse (10) are both inputted to polygonal saw-tooth wave generator 11 to generate polygonal saw-tooth wave (3) which synchronizes with wave (1) and has narrow-band sweep part C before and behind pulse (2).
