The Space Saver FAST TTL Gated Square Wave Generators manufactured by Engineered Components Company are designed to provide a square
wave output at a given frequency. These generators are both keyable and synchronizable, producing a continuous output train as long as a TTL
“low”isappliedtotheinput.WithaTTL“high”appliedtotheinput,output1willproduceaconstant“high”andoutput2willproduceaconstant
“low”. When the input switches to “low”, output 2 goes “high” immediately. Output 1 and output 2 both go low after one half-cycle and then run
in phase as a continuous square wave output. When the input switches back to “high”, output 2 goes “low” immediately and output 1 goes
“high”onehalf-cyclelater.
