ABSTRACT:
The video outputs of the correlators of a conventional IFM receiver are split by capacitors to obtain (1) pulse signals only and (2) pulse plus cw signals. Combining these signals in differential amplifiers, frequency readings are provided in the normal manner with the improvement that the individual frequency readings of simultaneously received pulse and cw signals are provided.
