hi, im wondering if anyone can help me with a revision problem i have... I understand the difference between synchronus = everything happens in time with the clock. Asynchronus = is it happens in time with the inputs. Therefore i need to create an Asynchronous circuit that have 2 inputs O(oscilation) and G(gate) and one output Z. O which is normaly low recieves a series of variable frequency and variable length (TTL pulses) which, under the control of G, are to be copied as accuratley as possible in length to the normaly low output of Z i need to do this using SR flip-flops and standard gates that meets the specification for a gated clock circuit. Thanks in advance for any help.
