Analogue Signal Calculator modules

QM

Quotient Module - Type 679 The Quotient Module is an analog divider which is used for calculating the ratio of two physiological input signals. Resistance can be calculated as the quotient of pressure to flow. For example to calculate the functional efficiency of a heart Q = dp/dtmin divided by dp/dtmax a Quotient Module is used. In this case the Quotient Module is connected to the Differentiator outputs MAX and MIN inside the PLUGSYS System. From these analogue outputs the Quotient Module calculates the quotient Q = dp/dtmin /dp/dtmax.

Description
Signal inputs	internally through links from PLUGSYS system bus (a) numerator (b) denominator
Input voltage range	–10 V to +10 V
Overrange	indicated by LEDs
Signal outputs	(a) BNC socket on front panel selected by switch N/D/Q (Numerator/Denominator/Quotient) (b) by jumpers via system bus: quotient
MUX signal output	on pressing the MUX key the signal selected on the N/D/Q switch is switched to the AM (Analog Multiplex) signal line
Rectifier	a 2-channel precision rectifier can be switched into the two inputs N and D through jumpers
Inverter	the two inputs N and D can have the input signal inverted through jumpers
