VEXCBL
Input SIG5 (VL = 0mV) to (A) and SIG1 (0dB,
100kHz, no burst) to (D) and assume that the
output amplitude (100kHz) of TP40 when COL =
128 is VCOCOL = 0 is VC2. Assume also that the
output amplitude of TP40 when SIG1 is -10dB and
COL=255 is VC1. Calculate as follows :
GEXCMX = 20log (VC1/VCO)+10
GEXCMN = 20log (VC2/VC0)
Input SIG5 (VL = 0mV) to (A) and SIG1 (0dB,
100kHz, no burst) to (D) and (E). Assume that the
output amplitude (100kHz) of TP40 is VB and that
