Input SIG4 (VL = 0mV) to (A) and SIG1 (0dB,
100kHz) 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 SIG4 (VL = 0mV) to (A) and SIG1 (0dB,
100kHz) to (D) and (E). Assume that the output
amplitude (100kHz) of TP40 is VB and that
(100kHz) of TP45 is VR. Calculate as follows :
