NAME: rbsp_dfb_response (function) PURPOSE: Calculate DFB responses at given frequencies. Two modes are suppored. If the sample rate keyword, SAMPLE_RATE, is specified, it will calculate the response of the low-pass output from DFB. If the the filter bank level keyword, FBK_LEVEL, is specified, it will calculate the response of the corresponding filter bank level. Warning: If both keywords are set, FBK_LEVEL is ignored. If neither is set, a NaN will be returned. Filter bank level look-up table: Frequency range in Hz | Level 8192 - 4096 | 1 4096 - 2048 | 2 2048 - 1024 | 3 1024 - 512 | 4 512 - 256 | 5 256 - 128 | 6 128 - 64 | 7 64 - 32 | 8 32 - 16 | 9 16 - 8 | 10 8 - 4 | 11 4 - 2 | 12 2 - 1 | 13 CATEGORIES: CALLING SEQUENCE: result = rbsp_dfb_response(f, sample_rate = sample_rate, $ fbk_level = fbk_level) ARGUMENTS: f: (Input, required) A floating array of frequencies at which the responses are calculated. KEYWORDS: sample_rate: (Input, optional) See PURPOSE. fbk_level: (Input, optional) See PURPOSE. COMMON BLOCKS: EXAMPLES: SEE ALSO: HISTORY: 2012-08-08: Created by Jianbao Tao (JBT), SSL, UC Berkley.
