31 * \brief This block generates a signal for FSK radar in baseband. The waveform consists
32 * of a signal with an alternating frequency. The packet length for subsequent tagged
33 * streams is calculated with two times the samples per single frequency multiplied by the
34 * blocks per tag.
35 *
36 * \param samp_rate Signal sample rate
37 * \param samp_per_freq Number of samples per frequency until the frequency shifts
38 * \param blocks_per_tag A block contains samp_per_freq samples of the low frequency and
39 * samp_per_freq samples of the high frequency. The packet length for subsequent tagged
40 * stream blocks is calculated with 2*samp_per_freq*blocks_per_tag. \param freq_low Lower
41 * frequency in baseband \param freq_high Higher frequency in baseband \param amplitude
42 * Signal amplitude \param len_key Packet length key for tagged stream
